Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145436, here are decompositions:
- 3 + 145433 = 145436
- 13 + 145423 = 145436
- 19 + 145417 = 145436
- 37 + 145399 = 145436
- 223 + 145213 = 145436
- 229 + 145207 = 145436
- 367 + 145069 = 145436
- 373 + 145063 = 145436
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 145,436 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 145436 first appears in π at position 425,949 of the decimal expansion (the 425,949ordinal-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.
