Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536346, here are decompositions:

53 + 31536293 = 31536346
59 + 31536287 = 31536346
293 + 31536053 = 31536346
467 + 31535879 = 31536346
593 + 31535753 = 31536346
599 + 31535747 = 31536346
797 + 31535549 = 31536346
929 + 31535417 = 31536346

Showing the first eight; more decompositions exist.
