Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147462228, here are decompositions:
- 31 + 2147462197 = 2147462228
- 139 + 2147462089 = 2147462228
- 151 + 2147462077 = 2147462228
- 181 + 2147462047 = 2147462228
- 199 + 2147462029 = 2147462228
- 211 + 2147462017 = 2147462228
- 337 + 2147461891 = 2147462228
- 421 + 2147461807 = 2147462228
Showing the first eight; more decompositions exist.
