Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609926, here are decompositions:

43 + 31609883 = 31609926
79 + 31609847 = 31609926
107 + 31609819 = 31609926
113 + 31609813 = 31609926
149 + 31609777 = 31609926
157 + 31609769 = 31609926
167 + 31609759 = 31609926
223 + 31609703 = 31609926

Showing the first eight; more decompositions exist.
