Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586002, here are decompositions:

5 + 31585997 = 31586002
23 + 31585979 = 31586002
29 + 31585973 = 31586002
113 + 31585889 = 31586002
179 + 31585823 = 31586002
191 + 31585811 = 31586002
251 + 31585751 = 31586002
311 + 31585691 = 31586002

Showing the first eight; more decompositions exist.
