Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527916, here are decompositions:

3 + 31527913 = 31527916
29 + 31527887 = 31527916
89 + 31527827 = 31527916
227 + 31527689 = 31527916
239 + 31527677 = 31527916
257 + 31527659 = 31527916
347 + 31527569 = 31527916
383 + 31527533 = 31527916

Showing the first eight; more decompositions exist.
