Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563708, here are decompositions:

37 + 31563671 = 31563708
61 + 31563647 = 31563708
107 + 31563601 = 31563708
139 + 31563569 = 31563708
157 + 31563551 = 31563708
181 + 31563527 = 31563708
257 + 31563451 = 31563708
277 + 31563431 = 31563708

Showing the first eight; more decompositions exist.
