Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520056, here are decompositions:

47 + 31520009 = 31520056
137 + 31519919 = 31520056
167 + 31519889 = 31520056
179 + 31519877 = 31520056
233 + 31519823 = 31520056
263 + 31519793 = 31520056
353 + 31519703 = 31520056
383 + 31519673 = 31520056

Showing the first eight; more decompositions exist.
