Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535768, here are decompositions:
- 97 + 31535671 = 31535768
- 349 + 31535419 = 31535768
- 457 + 31535311 = 31535768
- 541 + 31535227 = 31535768
- 661 + 31535107 = 31535768
- 709 + 31535059 = 31535768
- 757 + 31535011 = 31535768
- 769 + 31534999 = 31535768
Showing the first eight; more decompositions exist.
