Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527748, here are decompositions:

47 + 31527701 = 31527748
59 + 31527689 = 31527748
71 + 31527677 = 31527748
89 + 31527659 = 31527748
179 + 31527569 = 31527748
227 + 31527521 = 31527748
251 + 31527497 = 31527748
257 + 31527491 = 31527748

Showing the first eight; more decompositions exist.
