Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426218, here are decompositions:
- 11 + 2147426207 = 2147426218
- 59 + 2147426159 = 2147426218
- 71 + 2147426147 = 2147426218
- 101 + 2147426117 = 2147426218
- 137 + 2147426081 = 2147426218
- 239 + 2147425979 = 2147426218
- 281 + 2147425937 = 2147426218
- 347 + 2147425871 = 2147426218
Showing the first eight; more decompositions exist.
