Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513094, here are decompositions:

3 + 31513091 = 31513094
31 + 31513063 = 31513094
37 + 31513057 = 31513094
61 + 31513033 = 31513094
97 + 31512997 = 31513094
103 + 31512991 = 31513094
181 + 31512913 = 31513094
271 + 31512823 = 31513094

Showing the first eight; more decompositions exist.
