Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542696, here are decompositions:

19 + 31542677 = 31542696
37 + 31542659 = 31542696
83 + 31542613 = 31542696
109 + 31542587 = 31542696
137 + 31542559 = 31542696
149 + 31542547 = 31542696
173 + 31542523 = 31542696
239 + 31542457 = 31542696

Showing the first eight; more decompositions exist.
