Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520374, here are decompositions:

3 + 31520371 = 31520374
131 + 31520243 = 31520374
173 + 31520201 = 31520374
233 + 31520141 = 31520374
257 + 31520117 = 31520374
701 + 31519673 = 31520374
773 + 31519601 = 31520374
887 + 31519487 = 31520374

Showing the first eight; more decompositions exist.
