Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608526, here are decompositions:

29 + 31608497 = 31608526
263 + 31608263 = 31608526
359 + 31608167 = 31608526
419 + 31608107 = 31608526
479 + 31608047 = 31608526
557 + 31607969 = 31608526
617 + 31607909 = 31608526
659 + 31607867 = 31608526

Showing the first eight; more decompositions exist.
