Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609924, here are decompositions:

41 + 31609883 = 31609924
53 + 31609871 = 31609924
131 + 31609793 = 31609924
233 + 31609691 = 31609924
263 + 31609661 = 31609924
293 + 31609631 = 31609924
347 + 31609577 = 31609924
383 + 31609541 = 31609924

Showing the first eight; more decompositions exist.
