Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143406, here are decompositions:
- 5 + 143401 = 143406
- 19 + 143387 = 143406
- 73 + 143333 = 143406
- 149 + 143257 = 143406
- 157 + 143249 = 143406
- 163 + 143243 = 143406
- 167 + 143239 = 143406
- 229 + 143177 = 143406
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 143,406 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 143406 first appears in π at position 681,940 of the decimal expansion (the 681,940ordinal-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.
