Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78678, here are decompositions:
- 29 + 78649 = 78678
- 71 + 78607 = 78678
- 101 + 78577 = 78678
- 107 + 78571 = 78678
- 109 + 78569 = 78678
- 137 + 78541 = 78678
- 139 + 78539 = 78678
- 167 + 78511 = 78678
Showing the first eight; more decompositions exist.
