Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564762, here are decompositions:
- 23 + 31564739 = 31564762
- 41 + 31564721 = 31564762
- 101 + 31564661 = 31564762
- 113 + 31564649 = 31564762
- 149 + 31564613 = 31564762
- 401 + 31564361 = 31564762
- 431 + 31564331 = 31564762
- 491 + 31564271 = 31564762
Showing the first eight; more decompositions exist.
