Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622760, here are decompositions:
- 17 + 31622743 = 31622760
- 19 + 31622741 = 31622760
- 31 + 31622729 = 31622760
- 47 + 31622713 = 31622760
- 61 + 31622699 = 31622760
- 67 + 31622693 = 31622760
- 73 + 31622687 = 31622760
- 89 + 31622671 = 31622760
Showing the first eight; more decompositions exist.
