Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589400, here are decompositions:
- 23 + 31589377 = 31589400
- 41 + 31589359 = 31589400
- 47 + 31589353 = 31589400
- 61 + 31589339 = 31589400
- 67 + 31589333 = 31589400
- 71 + 31589329 = 31589400
- 79 + 31589321 = 31589400
- 83 + 31589317 = 31589400
Showing the first eight; more decompositions exist.
