Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527796, here are decompositions:

107 + 31527689 = 31527796
137 + 31527659 = 31527796
227 + 31527569 = 31527796
263 + 31527533 = 31527796
383 + 31527413 = 31527796
389 + 31527407 = 31527796
479 + 31527317 = 31527796
563 + 31527233 = 31527796

Showing the first eight; more decompositions exist.
