Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542710, here are decompositions:

7 + 31542703 = 31542710
13 + 31542697 = 31542710
79 + 31542631 = 31542710
97 + 31542613 = 31542710
151 + 31542559 = 31542710
163 + 31542547 = 31542710
223 + 31542487 = 31542710
271 + 31542439 = 31542710

Showing the first eight; more decompositions exist.
