Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38240, here are decompositions:
- 3 + 38237 = 38240
- 43 + 38197 = 38240
- 73 + 38167 = 38240
- 127 + 38113 = 38240
- 157 + 38083 = 38240
- 193 + 38047 = 38240
- 229 + 38011 = 38240
- 277 + 37963 = 38240
Showing the first eight; more decompositions exist.
