Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536934, here are decompositions:

17 + 31536917 = 31536934
71 + 31536863 = 31536934
113 + 31536821 = 31536934
227 + 31536707 = 31536934
383 + 31536551 = 31536934
587 + 31536347 = 31536934
641 + 31536293 = 31536934
647 + 31536287 = 31536934

Showing the first eight; more decompositions exist.
