Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1434, here are decompositions:
- 5 + 1429 = 1434
- 7 + 1427 = 1434
- 11 + 1423 = 1434
- 53 + 1381 = 1434
- 61 + 1373 = 1434
- 67 + 1367 = 1434
- 73 + 1361 = 1434
- 107 + 1327 = 1434
Showing the first eight; more decompositions exist.

The digit sequence 1434 first appears in π at position 4,172 of the decimal expansion (the 4,172ordinal-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.
