Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609092, here are decompositions:

5 + 31609087 = 31609092
13 + 31609079 = 31609092
43 + 31609049 = 31609092
59 + 31609033 = 31609092
61 + 31609031 = 31609092
139 + 31608953 = 31609092
181 + 31608911 = 31609092
199 + 31608893 = 31609092

Showing the first eight; more decompositions exist.
