Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623600, here are decompositions:
- 11 + 31623589 = 31623600
- 79 + 31623521 = 31623600
- 89 + 31623511 = 31623600
- 101 + 31623499 = 31623600
- 103 + 31623497 = 31623600
- 109 + 31623491 = 31623600
- 139 + 31623461 = 31623600
- 157 + 31623443 = 31623600
Showing the first eight; more decompositions exist.
