Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27758, here are decompositions:
- 7 + 27751 = 27758
- 19 + 27739 = 27758
- 61 + 27697 = 27758
- 67 + 27691 = 27758
- 127 + 27631 = 27758
- 229 + 27529 = 27758
- 271 + 27487 = 27758
- 277 + 27481 = 27758
Showing the first eight; more decompositions exist.
