Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542794, here are decompositions:

7 + 31542787 = 31542794
67 + 31542727 = 31542794
97 + 31542697 = 31542794
163 + 31542631 = 31542794
181 + 31542613 = 31542794
271 + 31542523 = 31542794
307 + 31542487 = 31542794
337 + 31542457 = 31542794

Showing the first eight; more decompositions exist.
