Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145046, here are decompositions:
- 3 + 145043 = 145046
- 37 + 145009 = 145046
- 73 + 144973 = 145046
- 79 + 144967 = 145046
- 157 + 144889 = 145046
- 163 + 144883 = 145046
- 199 + 144847 = 145046
- 229 + 144817 = 145046
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 145,046 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 145046 first appears in π at position 76,897 of the decimal expansion (the 76,897ordinal-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.
