Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583902, here are decompositions:
- 5 + 31583897 = 31583902
- 71 + 31583831 = 31583902
- 83 + 31583819 = 31583902
- 131 + 31583771 = 31583902
- 149 + 31583753 = 31583902
- 173 + 31583729 = 31583902
- 239 + 31583663 = 31583902
- 269 + 31583633 = 31583902
Showing the first eight; more decompositions exist.
