Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609032, here are decompositions:

61 + 31608971 = 31609032
73 + 31608959 = 31609032
79 + 31608953 = 31609032
139 + 31608893 = 31609032
149 + 31608883 = 31609032
179 + 31608853 = 31609032
181 + 31608851 = 31609032
211 + 31608821 = 31609032

Showing the first eight; more decompositions exist.
