Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63438, here are decompositions:
- 17 + 63421 = 63438
- 19 + 63419 = 63438
- 29 + 63409 = 63438
- 41 + 63397 = 63438
- 47 + 63391 = 63438
- 61 + 63377 = 63438
- 71 + 63367 = 63438
- 101 + 63337 = 63438
Showing the first eight; more decompositions exist.

The digit sequence 63438 first appears in π at position 246,315 of the decimal expansion (the 246,315ordinal-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.
