Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582672, here are decompositions:

5 + 31582667 = 31582672
41 + 31582631 = 31582672
59 + 31582613 = 31582672
71 + 31582601 = 31582672
83 + 31582589 = 31582672
113 + 31582559 = 31582672
263 + 31582409 = 31582672
269 + 31582403 = 31582672

Showing the first eight; more decompositions exist.
