Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527954, here are decompositions:

13 + 31527941 = 31527954
23 + 31527931 = 31527954
41 + 31527913 = 31527954
67 + 31527887 = 31527954
127 + 31527827 = 31527954
137 + 31527817 = 31527954
167 + 31527787 = 31527954
173 + 31527781 = 31527954

Showing the first eight; more decompositions exist.
