Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448070, here are decompositions:

13 + 31448057 = 31448070
37 + 31448033 = 31448070
47 + 31448023 = 31448070
53 + 31448017 = 31448070
83 + 31447987 = 31448070
103 + 31447967 = 31448070
107 + 31447963 = 31448070
109 + 31447961 = 31448070

Showing the first eight; more decompositions exist.
