Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609048, here are decompositions:

17 + 31609031 = 31609048
89 + 31608959 = 31609048
131 + 31608917 = 31609048
137 + 31608911 = 31609048
197 + 31608851 = 31609048
227 + 31608821 = 31609048
269 + 31608779 = 31609048
311 + 31608737 = 31609048

Showing the first eight; more decompositions exist.
