Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448054, here are decompositions:

31 + 31448023 = 31448054
37 + 31448017 = 31448054
67 + 31447987 = 31448054
97 + 31447957 = 31448054
103 + 31447951 = 31448054
151 + 31447903 = 31448054
241 + 31447813 = 31448054
271 + 31447783 = 31448054

Showing the first eight; more decompositions exist.
