Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507564, here are decompositions:

3 + 31507561 = 31507564
41 + 31507523 = 31507564
197 + 31507367 = 31507564
281 + 31507283 = 31507564
293 + 31507271 = 31507564
353 + 31507211 = 31507564
383 + 31507181 = 31507564
587 + 31506977 = 31507564

Showing the first eight; more decompositions exist.
