Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145708, here are decompositions:
- 5 + 145703 = 145708
- 29 + 145679 = 145708
- 47 + 145661 = 145708
- 71 + 145637 = 145708
- 107 + 145601 = 145708
- 131 + 145577 = 145708
- 191 + 145517 = 145708
- 197 + 145511 = 145708
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 145,708 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 145708 first appears in π at position 881,773 of the decimal expansion (the 881,773ordinal-suffix:rd 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.
