Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19626, here are decompositions:
- 17 + 19609 = 19626
- 23 + 19603 = 19626
- 29 + 19597 = 19626
- 43 + 19583 = 19626
- 67 + 19559 = 19626
- 73 + 19553 = 19626
- 83 + 19543 = 19626
- 137 + 19489 = 19626
Showing the first eight; more decompositions exist.
