Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507744, here are decompositions:

5 + 31507739 = 31507744
41 + 31507703 = 31507744
83 + 31507661 = 31507744
137 + 31507607 = 31507744
167 + 31507577 = 31507744
173 + 31507571 = 31507744
383 + 31507361 = 31507744
461 + 31507283 = 31507744

Showing the first eight; more decompositions exist.
