Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27718, here are decompositions:
- 17 + 27701 = 27718
- 29 + 27689 = 27718
- 71 + 27647 = 27718
- 101 + 27617 = 27718
- 107 + 27611 = 27718
- 137 + 27581 = 27718
- 167 + 27551 = 27718
- 179 + 27539 = 27718
Showing the first eight; more decompositions exist.
