Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625932, here are decompositions:

83 + 31625849 = 31625932
89 + 31625843 = 31625932
113 + 31625819 = 31625932
179 + 31625753 = 31625932
251 + 31625681 = 31625932
281 + 31625651 = 31625932
353 + 31625579 = 31625932
479 + 31625453 = 31625932

Showing the first eight; more decompositions exist.
