Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422798, here are decompositions:
- 71 + 2147422727 = 2147422798
- 107 + 2147422691 = 2147422798
- 149 + 2147422649 = 2147422798
- 239 + 2147422559 = 2147422798
- 317 + 2147422481 = 2147422798
- 467 + 2147422331 = 2147422798
- 557 + 2147422241 = 2147422798
- 569 + 2147422229 = 2147422798
Showing the first eight; more decompositions exist.
