Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595520, here are decompositions:
- 37 + 31595483 = 31595520
- 53 + 31595467 = 31595520
- 113 + 31595407 = 31595520
- 127 + 31595393 = 31595520
- 137 + 31595383 = 31595520
- 149 + 31595371 = 31595520
- 157 + 31595363 = 31595520
- 241 + 31595279 = 31595520
Showing the first eight; more decompositions exist.
