Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609582, here are decompositions:

5 + 31609577 = 31609582
41 + 31609541 = 31609582
83 + 31609499 = 31609582
89 + 31609493 = 31609582
101 + 31609481 = 31609582
113 + 31609469 = 31609582
131 + 31609451 = 31609582
293 + 31609289 = 31609582

Showing the first eight; more decompositions exist.
