Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595590, here are decompositions:
- 17 + 31595573 = 31595590
- 23 + 31595567 = 31595590
- 107 + 31595483 = 31595590
- 197 + 31595393 = 31595590
- 227 + 31595363 = 31595590
- 311 + 31595279 = 31595590
- 317 + 31595273 = 31595590
- 347 + 31595243 = 31595590
Showing the first eight; more decompositions exist.
