Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426188, here are decompositions:
- 29 + 2147426159 = 2147426188
- 41 + 2147426147 = 2147426188
- 71 + 2147426117 = 2147426188
- 107 + 2147426081 = 2147426188
- 251 + 2147425937 = 2147426188
- 317 + 2147425871 = 2147426188
- 647 + 2147425541 = 2147426188
- 839 + 2147425349 = 2147426188
Showing the first eight; more decompositions exist.
