Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484376, here are decompositions:
- 13 + 31484363 = 31484376
- 17 + 31484359 = 31484376
- 23 + 31484353 = 31484376
- 37 + 31484339 = 31484376
- 59 + 31484317 = 31484376
- 73 + 31484303 = 31484376
- 109 + 31484267 = 31484376
- 137 + 31484239 = 31484376
Showing the first eight; more decompositions exist.
