Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30642, here are decompositions:
- 5 + 30637 = 30642
- 11 + 30631 = 30642
- 83 + 30559 = 30642
- 89 + 30553 = 30642
- 103 + 30539 = 30642
- 113 + 30529 = 30642
- 149 + 30493 = 30642
- 151 + 30491 = 30642
Showing the first eight; more decompositions exist.
