Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609552, here are decompositions:

3 + 31609549 = 31609552
5 + 31609547 = 31609552
11 + 31609541 = 31609552
53 + 31609499 = 31609552
59 + 31609493 = 31609552
71 + 31609481 = 31609552
83 + 31609469 = 31609552
89 + 31609463 = 31609552

Showing the first eight; more decompositions exist.
