Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606012, here are decompositions:

29 + 31605983 = 31606012
41 + 31605971 = 31606012
59 + 31605953 = 31606012
83 + 31605929 = 31606012
233 + 31605779 = 31606012
239 + 31605773 = 31606012
293 + 31605719 = 31606012
311 + 31605701 = 31606012

Showing the first eight; more decompositions exist.
