Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145766, here are decompositions:
- 7 + 145759 = 145766
- 13 + 145753 = 145766
- 43 + 145723 = 145766
- 79 + 145687 = 145766
- 163 + 145603 = 145766
- 223 + 145543 = 145766
- 307 + 145459 = 145766
- 349 + 145417 = 145766
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 145,766 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 145766 first appears in π at position 340,228 of the decimal expansion (the 340,228ordinal-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.
