Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583242, here are decompositions:
- 71 + 31583171 = 31583242
- 83 + 31583159 = 31583242
- 191 + 31583051 = 31583242
- 281 + 31582961 = 31583242
- 293 + 31582949 = 31583242
- 311 + 31582931 = 31583242
- 419 + 31582823 = 31583242
- 461 + 31582781 = 31583242
Showing the first eight; more decompositions exist.
