Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55428, here are decompositions:
- 17 + 55411 = 55428
- 29 + 55399 = 55428
- 47 + 55381 = 55428
- 89 + 55339 = 55428
- 97 + 55331 = 55428
- 137 + 55291 = 55428
- 179 + 55249 = 55428
- 199 + 55229 = 55428
Showing the first eight; more decompositions exist.

The digit sequence 55428 first appears in π at position 261,204 of the decimal expansion (the 261,204ordinal-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.
