Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018248, here are decompositions:
- 31 + 1018217 = 1018248
- 41 + 1018207 = 1018248
- 47 + 1018201 = 1018248
- 71 + 1018177 = 1018248
- 139 + 1018109 = 1018248
- 151 + 1018097 = 1018248
- 157 + 1018091 = 1018248
- 191 + 1018057 = 1018248
Showing the first eight; more decompositions exist.
