Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461132, here are decompositions:

5 + 31461127 = 31461132
19 + 31461113 = 31461132
83 + 31461049 = 31461132
181 + 31460951 = 31461132
281 + 31460851 = 31461132
293 + 31460839 = 31461132
349 + 31460783 = 31461132
389 + 31460743 = 31461132

Showing the first eight; more decompositions exist.
