Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507054, here are decompositions:

17 + 31507037 = 31507054
167 + 31506887 = 31507054
233 + 31506821 = 31507054
263 + 31506791 = 31507054
311 + 31506743 = 31507054
617 + 31506437 = 31507054
701 + 31506353 = 31507054
743 + 31506311 = 31507054

Showing the first eight; more decompositions exist.
