Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27660, here are decompositions:
- 7 + 27653 = 27660
- 13 + 27647 = 27660
- 29 + 27631 = 27660
- 43 + 27617 = 27660
- 79 + 27581 = 27660
- 109 + 27551 = 27660
- 131 + 27529 = 27660
- 151 + 27509 = 27660
Showing the first eight; more decompositions exist.
