Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143078, here are decompositions:
- 97 + 142981 = 143078
- 109 + 142969 = 143078
- 139 + 142939 = 143078
- 181 + 142897 = 143078
- 211 + 142867 = 143078
- 241 + 142837 = 143078
- 307 + 142771 = 143078
- 367 + 142711 = 143078
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 143,078 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 143078 first appears in π at position 586,149 of the decimal expansion (the 586,149ordinal-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.
