Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145750, here are decompositions:
- 29 + 145721 = 145750
- 41 + 145709 = 145750
- 47 + 145703 = 145750
- 71 + 145679 = 145750
- 89 + 145661 = 145750
- 107 + 145643 = 145750
- 113 + 145637 = 145750
- 149 + 145601 = 145750
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 145,750 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 145750 first appears in π at position 21,448 of the decimal expansion (the 21,448ordinal-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.
