Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609762, here are decompositions:

3 + 31609759 = 31609762
59 + 31609703 = 31609762
71 + 31609691 = 31609762
83 + 31609679 = 31609762
101 + 31609661 = 31609762
131 + 31609631 = 31609762
179 + 31609583 = 31609762
263 + 31609499 = 31609762

Showing the first eight; more decompositions exist.
