Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544896, here are decompositions:

17 + 31544879 = 31544896
113 + 31544783 = 31544896
137 + 31544759 = 31544896
179 + 31544717 = 31544896
239 + 31544657 = 31544896
353 + 31544543 = 31544896
479 + 31544417 = 31544896
503 + 31544393 = 31544896

Showing the first eight; more decompositions exist.
