Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28624, here are decompositions:
- 3 + 28621 = 28624
- 5 + 28619 = 28624
- 17 + 28607 = 28624
- 53 + 28571 = 28624
- 83 + 28541 = 28624
- 107 + 28517 = 28624
- 131 + 28493 = 28624
- 191 + 28433 = 28624
Showing the first eight; more decompositions exist.
