Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542774, here are decompositions:

7 + 31542767 = 31542774
47 + 31542727 = 31542774
71 + 31542703 = 31542774
97 + 31542677 = 31542774
227 + 31542547 = 31542774
251 + 31542523 = 31542774
317 + 31542457 = 31542774
337 + 31542437 = 31542774

Showing the first eight; more decompositions exist.
