Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557850, here are decompositions:
- 17 + 31557833 = 31557850
- 41 + 31557809 = 31557850
- 59 + 31557791 = 31557850
- 89 + 31557761 = 31557850
- 101 + 31557749 = 31557850
- 167 + 31557683 = 31557850
- 173 + 31557677 = 31557850
- 179 + 31557671 = 31557850
Showing the first eight; more decompositions exist.
