Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38628, here are decompositions:
- 17 + 38611 = 38628
- 19 + 38609 = 38628
- 59 + 38569 = 38628
- 61 + 38567 = 38628
- 67 + 38561 = 38628
- 71 + 38557 = 38628
- 127 + 38501 = 38628
- 167 + 38461 = 38628
Showing the first eight; more decompositions exist.
