Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609792, here are decompositions:

23 + 31609769 = 31609792
89 + 31609703 = 31609792
101 + 31609691 = 31609792
113 + 31609679 = 31609792
131 + 31609661 = 31609792
251 + 31609541 = 31609792
293 + 31609499 = 31609792
311 + 31609481 = 31609792

Showing the first eight; more decompositions exist.
