Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507804, here are decompositions:

11 + 31507793 = 31507804
17 + 31507787 = 31507804
101 + 31507703 = 31507804
137 + 31507667 = 31507804
197 + 31507607 = 31507804
227 + 31507577 = 31507804
233 + 31507571 = 31507804
281 + 31507523 = 31507804

Showing the first eight; more decompositions exist.
