Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561282, here are decompositions:
- 41 + 31561241 = 31561282
- 83 + 31561199 = 31561282
- 239 + 31561043 = 31561282
- 281 + 31561001 = 31561282
- 419 + 31560863 = 31561282
- 491 + 31560791 = 31561282
- 563 + 31560719 = 31561282
- 569 + 31560713 = 31561282
Showing the first eight; more decompositions exist.
