Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536374, here are decompositions:

13 + 31536361 = 31536374
61 + 31536313 = 31536374
151 + 31536223 = 31536374
277 + 31536097 = 31536374
313 + 31536061 = 31536374
433 + 31535941 = 31536374
547 + 31535827 = 31536374
577 + 31535797 = 31536374

Showing the first eight; more decompositions exist.
