Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609504, here are decompositions:

5 + 31609499 = 31609504
11 + 31609493 = 31609504
23 + 31609481 = 31609504
41 + 31609463 = 31609504
53 + 31609451 = 31609504
281 + 31609223 = 31609504
587 + 31608917 = 31609504
593 + 31608911 = 31609504

Showing the first eight; more decompositions exist.
