Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609612, here are decompositions:

3 + 31609609 = 31609612
29 + 31609583 = 31609612
71 + 31609541 = 31609612
113 + 31609499 = 31609612
131 + 31609481 = 31609612
149 + 31609463 = 31609612
383 + 31609229 = 31609612
389 + 31609223 = 31609612

Showing the first eight; more decompositions exist.
