Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40238, here are decompositions:
- 7 + 40231 = 40238
- 61 + 40177 = 40238
- 109 + 40129 = 40238
- 127 + 40111 = 40238
- 139 + 40099 = 40238
- 151 + 40087 = 40238
- 199 + 40039 = 40238
- 229 + 40009 = 40238
Showing the first eight; more decompositions exist.
