Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045500, here are decompositions:
- 7 + 1045493 = 1045500
- 13 + 1045487 = 1045500
- 31 + 1045469 = 1045500
- 73 + 1045427 = 1045500
- 89 + 1045411 = 1045500
- 103 + 1045397 = 1045500
- 107 + 1045393 = 1045500
- 109 + 1045391 = 1045500
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 1,045,500 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 1045500 first appears in π at position 160,245 of the decimal expansion (the 160,245ordinal-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.
