Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527736, here are decompositions:

47 + 31527689 = 31527736
59 + 31527677 = 31527736
167 + 31527569 = 31527736
239 + 31527497 = 31527736
347 + 31527389 = 31527736
419 + 31527317 = 31527736
503 + 31527233 = 31527736
563 + 31527173 = 31527736

Showing the first eight; more decompositions exist.
