Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70812, here are decompositions:
- 19 + 70793 = 70812
- 29 + 70783 = 70812
- 43 + 70769 = 70812
- 59 + 70753 = 70812
- 83 + 70729 = 70812
- 103 + 70709 = 70812
- 149 + 70663 = 70812
- 173 + 70639 = 70812
Showing the first eight; more decompositions exist.
