Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583760, here are decompositions:
- 7 + 31583753 = 31583760
- 11 + 31583749 = 31583760
- 31 + 31583729 = 31583760
- 59 + 31583701 = 31583760
- 67 + 31583693 = 31583760
- 73 + 31583687 = 31583760
- 97 + 31583663 = 31583760
- 101 + 31583659 = 31583760
Showing the first eight; more decompositions exist.
