Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609624, here are decompositions:

41 + 31609583 = 31609624
47 + 31609577 = 31609624
83 + 31609541 = 31609624
131 + 31609493 = 31609624
173 + 31609451 = 31609624
401 + 31609223 = 31609624
593 + 31609031 = 31609624
653 + 31608971 = 31609624

Showing the first eight; more decompositions exist.
