Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609854, here are decompositions:

5 + 31609849 = 31609854
7 + 31609847 = 31609854
41 + 31609813 = 31609854
61 + 31609793 = 31609854
113 + 31609741 = 31609854
131 + 31609723 = 31609854
151 + 31609703 = 31609854
163 + 31609691 = 31609854

Showing the first eight; more decompositions exist.
