Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529094, here are decompositions:

5 + 31529089 = 31529094
7 + 31529087 = 31529094
13 + 31529081 = 31529094
41 + 31529053 = 31529094
97 + 31528997 = 31529094
101 + 31528993 = 31529094
127 + 31528967 = 31529094
241 + 31528853 = 31529094

Showing the first eight; more decompositions exist.
