Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147389792, here are decompositions:
- 11 + 2147389781 = 2147389792
- 29 + 2147389763 = 2147389792
- 101 + 2147389691 = 2147389792
- 113 + 2147389679 = 2147389792
- 173 + 2147389619 = 2147389792
- 269 + 2147389523 = 2147389792
- 389 + 2147389403 = 2147389792
- 461 + 2147389331 = 2147389792
Showing the first eight; more decompositions exist.
