Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586066, here are decompositions:

7 + 31586059 = 31586066
13 + 31586053 = 31586066
103 + 31585963 = 31586066
163 + 31585903 = 31586066
229 + 31585837 = 31586066
283 + 31585783 = 31586066
487 + 31585579 = 31586066
607 + 31585459 = 31586066

Showing the first eight; more decompositions exist.
