Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78672, here are decompositions:
- 19 + 78653 = 78672
- 23 + 78649 = 78672
- 29 + 78643 = 78672
- 79 + 78593 = 78672
- 89 + 78583 = 78672
- 101 + 78571 = 78672
- 103 + 78569 = 78672
- 131 + 78541 = 78672
Showing the first eight; more decompositions exist.
