Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6628, here are decompositions:
- 29 + 6599 = 6628
- 47 + 6581 = 6628
- 59 + 6569 = 6628
- 107 + 6521 = 6628
- 137 + 6491 = 6628
- 179 + 6449 = 6628
- 239 + 6389 = 6628
- 269 + 6359 = 6628
Showing the first eight; more decompositions exist.
