Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528054, here are decompositions:

17 + 31528037 = 31528054
53 + 31528001 = 31528054
113 + 31527941 = 31528054
167 + 31527887 = 31528054
227 + 31527827 = 31528054
353 + 31527701 = 31528054
521 + 31527533 = 31528054
557 + 31527497 = 31528054

Showing the first eight; more decompositions exist.
