Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609576, here are decompositions:

29 + 31609547 = 31609576
83 + 31609493 = 31609576
107 + 31609469 = 31609576
113 + 31609463 = 31609576
347 + 31609229 = 31609576
353 + 31609223 = 31609576
617 + 31608959 = 31609576
659 + 31608917 = 31609576

Showing the first eight; more decompositions exist.
