Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28616, here are decompositions:
- 13 + 28603 = 28616
- 19 + 28597 = 28616
- 37 + 28579 = 28616
- 43 + 28573 = 28616
- 67 + 28549 = 28616
- 79 + 28537 = 28616
- 103 + 28513 = 28616
- 139 + 28477 = 28616
Showing the first eight; more decompositions exist.
