Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622390, here are decompositions:
- 13 + 31622377 = 31622390
- 43 + 31622347 = 31622390
- 97 + 31622293 = 31622390
- 103 + 31622287 = 31622390
- 109 + 31622281 = 31622390
- 211 + 31622179 = 31622390
- 223 + 31622167 = 31622390
- 271 + 31622119 = 31622390
Showing the first eight; more decompositions exist.
