Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527966, here are decompositions:

53 + 31527913 = 31527966
79 + 31527887 = 31527966
137 + 31527829 = 31527966
139 + 31527827 = 31527966
149 + 31527817 = 31527966
179 + 31527787 = 31527966
257 + 31527709 = 31527966
263 + 31527703 = 31527966

Showing the first eight; more decompositions exist.
