Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448094, here are decompositions:

23 + 31448071 = 31448094
37 + 31448057 = 31448094
61 + 31448033 = 31448094
71 + 31448023 = 31448094
107 + 31447987 = 31448094
127 + 31447967 = 31448094
131 + 31447963 = 31448094
137 + 31447957 = 31448094

Showing the first eight; more decompositions exist.
