Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507606, here are decompositions:

23 + 31507583 = 31507606
29 + 31507577 = 31507606
83 + 31507523 = 31507606
239 + 31507367 = 31507606
467 + 31507139 = 31507606
569 + 31507037 = 31507606
677 + 31506929 = 31507606
719 + 31506887 = 31507606

Showing the first eight; more decompositions exist.
