Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486516, here are decompositions:
- 23 + 31486493 = 31486516
- 53 + 31486463 = 31486516
- 59 + 31486457 = 31486516
- 167 + 31486349 = 31486516
- 179 + 31486337 = 31486516
- 227 + 31486289 = 31486516
- 233 + 31486283 = 31486516
- 263 + 31486253 = 31486516
Showing the first eight; more decompositions exist.
