Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738240, here are decompositions:
- 13 + 8738227 = 8738240
- 31 + 8738209 = 8738240
- 79 + 8738161 = 8738240
- 139 + 8738101 = 8738240
- 151 + 8738089 = 8738240
- 157 + 8738083 = 8738240
- 193 + 8738047 = 8738240
- 229 + 8738011 = 8738240
Showing the first eight; more decompositions exist.
