Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048040, here are decompositions:
- 13 + 1048027 = 1048040
- 31 + 1048009 = 1048040
- 43 + 1047997 = 1048040
- 61 + 1047979 = 1048040
- 79 + 1047961 = 1048040
- 157 + 1047883 = 1048040
- 181 + 1047859 = 1048040
- 199 + 1047841 = 1048040
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,048,040 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1048040 first appears in π at position 754,840 of the decimal expansion (the 754,840ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
