Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607544, here are decompositions:

13 + 31607531 = 31607544
41 + 31607503 = 31607544
71 + 31607473 = 31607544
83 + 31607461 = 31607544
97 + 31607447 = 31607544
181 + 31607363 = 31607544
251 + 31607293 = 31607544
263 + 31607281 = 31607544

Showing the first eight; more decompositions exist.
