Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580096, here are decompositions:

3 + 31580093 = 31580096
13 + 31580083 = 31580096
19 + 31580077 = 31580096
43 + 31580053 = 31580096
127 + 31579969 = 31580096
277 + 31579819 = 31580096
283 + 31579813 = 31580096
349 + 31579747 = 31580096

Showing the first eight; more decompositions exist.
