Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559760, here are decompositions:
- 41 + 31559719 = 31559760
- 61 + 31559699 = 31559760
- 73 + 31559687 = 31559760
- 79 + 31559681 = 31559760
- 83 + 31559677 = 31559760
- 101 + 31559659 = 31559760
- 107 + 31559653 = 31559760
- 109 + 31559651 = 31559760
Showing the first eight; more decompositions exist.
