Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514742, here are decompositions:

11 + 31514731 = 31514742
53 + 31514689 = 31514742
71 + 31514671 = 31514742
79 + 31514663 = 31514742
89 + 31514653 = 31514742
101 + 31514641 = 31514742
113 + 31514629 = 31514742
163 + 31514579 = 31514742

Showing the first eight; more decompositions exist.
