Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483856, here are decompositions:

37 + 31483819 = 31483856
67 + 31483789 = 31483856
97 + 31483759 = 31483856
193 + 31483663 = 31483856
307 + 31483549 = 31483856
409 + 31483447 = 31483856
487 + 31483369 = 31483856
619 + 31483237 = 31483856

Showing the first eight; more decompositions exist.
