Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28646, here are decompositions:
- 3 + 28643 = 28646
- 19 + 28627 = 28646
- 43 + 28603 = 28646
- 67 + 28579 = 28646
- 73 + 28573 = 28646
- 97 + 28549 = 28646
- 109 + 28537 = 28646
- 199 + 28447 = 28646
Showing the first eight; more decompositions exist.
