Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609060, here are decompositions:

11 + 31609049 = 31609060
29 + 31609031 = 31609060
89 + 31608971 = 31609060
101 + 31608959 = 31609060
107 + 31608953 = 31609060
149 + 31608911 = 31609060
167 + 31608893 = 31609060
173 + 31608887 = 31609060

Showing the first eight; more decompositions exist.
