Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547696, here are decompositions:

3 + 31547693 = 31547696
13 + 31547683 = 31547696
67 + 31547629 = 31547696
79 + 31547617 = 31547696
139 + 31547557 = 31547696
157 + 31547539 = 31547696
283 + 31547413 = 31547696
379 + 31547317 = 31547696

Showing the first eight; more decompositions exist.
