Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583106, here are decompositions:
- 19 + 31583087 = 31583106
- 59 + 31583047 = 31583106
- 73 + 31583033 = 31583106
- 83 + 31583023 = 31583106
- 157 + 31582949 = 31583106
- 193 + 31582913 = 31583106
- 199 + 31582907 = 31583106
- 283 + 31582823 = 31583106
Showing the first eight; more decompositions exist.
