Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39242, here are decompositions:
- 3 + 39239 = 39242
- 13 + 39229 = 39242
- 43 + 39199 = 39242
- 61 + 39181 = 39242
- 79 + 39163 = 39242
- 103 + 39139 = 39242
- 109 + 39133 = 39242
- 139 + 39103 = 39242
Showing the first eight; more decompositions exist.
