Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517488, here are decompositions:
- 47 + 31517441 = 31517488
- 71 + 31517417 = 31517488
- 89 + 31517399 = 31517488
- 257 + 31517231 = 31517488
- 281 + 31517207 = 31517488
- 449 + 31517039 = 31517488
- 461 + 31517027 = 31517488
- 467 + 31517021 = 31517488
Showing the first eight; more decompositions exist.
