Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496932, here are decompositions:

11 + 31496921 = 31496932
59 + 31496873 = 31496932
113 + 31496819 = 31496932
149 + 31496783 = 31496932
191 + 31496741 = 31496932
239 + 31496693 = 31496932
263 + 31496669 = 31496932
359 + 31496573 = 31496932

Showing the first eight; more decompositions exist.
