Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486216, here are decompositions:
- 53 + 31486163 = 31486216
- 107 + 31486109 = 31486216
- 257 + 31485959 = 31486216
- 263 + 31485953 = 31486216
- 383 + 31485833 = 31486216
- 449 + 31485767 = 31486216
- 467 + 31485749 = 31486216
- 479 + 31485737 = 31486216
Showing the first eight; more decompositions exist.
