Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587696, here are decompositions:

37 + 31587659 = 31587696
73 + 31587623 = 31587696
79 + 31587617 = 31587696
109 + 31587587 = 31587696
199 + 31587497 = 31587696
223 + 31587473 = 31587696
263 + 31587433 = 31587696
269 + 31587427 = 31587696

Showing the first eight; more decompositions exist.
