Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12628, here are decompositions:
- 17 + 12611 = 12628
- 59 + 12569 = 12628
- 89 + 12539 = 12628
- 101 + 12527 = 12628
- 131 + 12497 = 12628
- 137 + 12491 = 12628
- 149 + 12479 = 12628
- 191 + 12437 = 12628
Showing the first eight; more decompositions exist.
