Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609002, here are decompositions:

31 + 31608971 = 31609002
43 + 31608959 = 31609002
109 + 31608893 = 31609002
149 + 31608853 = 31609002
151 + 31608851 = 31609002
179 + 31608823 = 31609002
181 + 31608821 = 31609002
223 + 31608779 = 31609002

Showing the first eight; more decompositions exist.
