Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523696, here are decompositions:

37 + 31523659 = 31523696
97 + 31523599 = 31523696
157 + 31523539 = 31523696
223 + 31523473 = 31523696
229 + 31523467 = 31523696
277 + 31523419 = 31523696
349 + 31523347 = 31523696
367 + 31523329 = 31523696

Showing the first eight; more decompositions exist.
