Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475094, here are decompositions:

5 + 31475089 = 31475094
11 + 31475083 = 31475094
23 + 31475071 = 31475094
41 + 31475053 = 31475094
97 + 31474997 = 31475094
113 + 31474981 = 31475094
163 + 31474931 = 31475094
227 + 31474867 = 31475094

Showing the first eight; more decompositions exist.
