Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536770, here are decompositions:

37 + 31536733 = 31536770
73 + 31536697 = 31536770
157 + 31536613 = 31536770
163 + 31536607 = 31536770
241 + 31536529 = 31536770
271 + 31536499 = 31536770
367 + 31536403 = 31536770
373 + 31536397 = 31536770

Showing the first eight; more decompositions exist.
