Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609654, here are decompositions:

23 + 31609631 = 31609654
71 + 31609583 = 31609654
107 + 31609547 = 31609654
113 + 31609541 = 31609654
173 + 31609481 = 31609654
191 + 31609463 = 31609654
431 + 31609223 = 31609654
563 + 31609091 = 31609654

Showing the first eight; more decompositions exist.
