Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78624, here are decompositions:
- 17 + 78607 = 78624
- 31 + 78593 = 78624
- 41 + 78583 = 78624
- 47 + 78577 = 78624
- 53 + 78571 = 78624
- 71 + 78553 = 78624
- 83 + 78541 = 78624
- 107 + 78517 = 78624
Showing the first eight; more decompositions exist.
