Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12658, here are decompositions:
- 5 + 12653 = 12658
- 11 + 12647 = 12658
- 17 + 12641 = 12658
- 47 + 12611 = 12658
- 89 + 12569 = 12658
- 131 + 12527 = 12658
- 167 + 12491 = 12658
- 179 + 12479 = 12658
Showing the first eight; more decompositions exist.
