Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143426, here are decompositions:
- 7 + 143419 = 143426
- 13 + 143413 = 143426
- 97 + 143329 = 143426
- 139 + 143287 = 143426
- 163 + 143263 = 143426
- 229 + 143197 = 143426
- 313 + 143113 = 143426
- 373 + 143053 = 143426
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 143,426 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 143426 first appears in π at position 130,332 of the decimal expansion (the 130,332ordinal-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.
