Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145764, here are decompositions:
- 5 + 145759 = 145764
- 7 + 145757 = 145764
- 11 + 145753 = 145764
- 41 + 145723 = 145764
- 43 + 145721 = 145764
- 61 + 145703 = 145764
- 83 + 145681 = 145764
- 103 + 145661 = 145764
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 145,764 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 145764 first appears in π at position 721,182 of the decimal expansion (the 721,182ordinal-suffix:nd 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.
