Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523576, here are decompositions:

37 + 31523539 = 31523576
103 + 31523473 = 31523576
109 + 31523467 = 31523576
157 + 31523419 = 31523576
229 + 31523347 = 31523576
283 + 31523293 = 31523576
349 + 31523227 = 31523576
367 + 31523209 = 31523576

Showing the first eight; more decompositions exist.
