Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422774, here are decompositions:
- 47 + 2147422727 = 2147422774
- 71 + 2147422703 = 2147422774
- 83 + 2147422691 = 2147422774
- 281 + 2147422493 = 2147422774
- 293 + 2147422481 = 2147422774
- 311 + 2147422463 = 2147422774
- 317 + 2147422457 = 2147422774
- 401 + 2147422373 = 2147422774
Showing the first eight; more decompositions exist.
