Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27664, here are decompositions:
- 11 + 27653 = 27664
- 17 + 27647 = 27664
- 47 + 27617 = 27664
- 53 + 27611 = 27664
- 83 + 27581 = 27664
- 113 + 27551 = 27664
- 137 + 27527 = 27664
- 227 + 27437 = 27664
Showing the first eight; more decompositions exist.
