Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497122, here are decompositions:
- 313 + 31496809 = 31497122
- 331 + 31496791 = 31497122
- 523 + 31496599 = 31497122
- 571 + 31496551 = 31497122
- 673 + 31496449 = 31497122
- 733 + 31496389 = 31497122
- 751 + 31496371 = 31497122
- 829 + 31496293 = 31497122
Showing the first eight; more decompositions exist.
