Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523690, here are decompositions:
- 31 + 31523659 = 31523690
- 43 + 31523647 = 31523690
- 151 + 31523539 = 31523690
- 223 + 31523467 = 31523690
- 229 + 31523461 = 31523690
- 271 + 31523419 = 31523690
- 283 + 31523407 = 31523690
- 397 + 31523293 = 31523690
Showing the first eight; more decompositions exist.
