Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534812, here are decompositions:
- 11 + 31534801 = 31534812
- 13 + 31534799 = 31534812
- 59 + 31534753 = 31534812
- 61 + 31534751 = 31534812
- 73 + 31534739 = 31534812
- 83 + 31534729 = 31534812
- 103 + 31534709 = 31534812
- 181 + 31534631 = 31534812
Showing the first eight; more decompositions exist.
