Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17562, here are decompositions:
- 11 + 17551 = 17562
- 23 + 17539 = 17562
- 43 + 17519 = 17562
- 53 + 17509 = 17562
- 71 + 17491 = 17562
- 73 + 17489 = 17562
- 79 + 17483 = 17562
- 113 + 17449 = 17562
Showing the first eight; more decompositions exist.
