Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534650, here are decompositions:
- 13 + 31534637 = 31534650
- 19 + 31534631 = 31534650
- 53 + 31534597 = 31534650
- 61 + 31534589 = 31534650
- 89 + 31534561 = 31534650
- 97 + 31534553 = 31534650
- 107 + 31534543 = 31534650
- 149 + 31534501 = 31534650
Showing the first eight; more decompositions exist.
