Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448066, here are decompositions:

43 + 31448023 = 31448066
79 + 31447987 = 31448066
103 + 31447963 = 31448066
109 + 31447957 = 31448066
163 + 31447903 = 31448066
229 + 31447837 = 31448066
283 + 31447783 = 31448066
409 + 31447657 = 31448066

Showing the first eight; more decompositions exist.
