Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89728, here are decompositions:
- 47 + 89681 = 89728
- 59 + 89669 = 89728
- 71 + 89657 = 89728
- 101 + 89627 = 89728
- 131 + 89597 = 89728
- 137 + 89591 = 89728
- 167 + 89561 = 89728
- 227 + 89501 = 89728
Showing the first eight; more decompositions exist.
