Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30684, here are decompositions:
- 7 + 30677 = 30684
- 13 + 30671 = 30684
- 23 + 30661 = 30684
- 41 + 30643 = 30684
- 47 + 30637 = 30684
- 53 + 30631 = 30684
- 107 + 30577 = 30684
- 127 + 30557 = 30684
Showing the first eight; more decompositions exist.
