Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496850, here are decompositions:
- 23 + 31496827 = 31496850
- 31 + 31496819 = 31496850
- 41 + 31496809 = 31496850
- 59 + 31496791 = 31496850
- 67 + 31496783 = 31496850
- 71 + 31496779 = 31496850
- 109 + 31496741 = 31496850
- 131 + 31496719 = 31496850
Showing the first eight; more decompositions exist.
