Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422898, here are decompositions:
- 7 + 2147422891 = 2147422898
- 37 + 2147422861 = 2147422898
- 79 + 2147422819 = 2147422898
- 109 + 2147422789 = 2147422898
- 151 + 2147422747 = 2147422898
- 241 + 2147422657 = 2147422898
- 349 + 2147422549 = 2147422898
- 409 + 2147422489 = 2147422898
Showing the first eight; more decompositions exist.
