Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507546, here are decompositions:

23 + 31507523 = 31507546
179 + 31507367 = 31507546
227 + 31507319 = 31507546
263 + 31507283 = 31507546
347 + 31507199 = 31507546
509 + 31507037 = 31507546
569 + 31506977 = 31507546
617 + 31506929 = 31507546

Showing the first eight; more decompositions exist.
