Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448060, here are decompositions:

3 + 31448057 = 31448060
37 + 31448023 = 31448060
43 + 31448017 = 31448060
73 + 31447987 = 31448060
97 + 31447963 = 31448060
103 + 31447957 = 31448060
109 + 31447951 = 31448060
157 + 31447903 = 31448060

Showing the first eight; more decompositions exist.
