Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589460, here are decompositions:
- 37 + 31589423 = 31589460
- 53 + 31589407 = 31589460
- 59 + 31589401 = 31589460
- 83 + 31589377 = 31589460
- 101 + 31589359 = 31589460
- 107 + 31589353 = 31589460
- 127 + 31589333 = 31589460
- 131 + 31589329 = 31589460
Showing the first eight; more decompositions exist.
