Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608506, here are decompositions:

79 + 31608427 = 31608506
157 + 31608349 = 31608506
337 + 31608169 = 31608506
373 + 31608133 = 31608506
439 + 31608067 = 31608506
823 + 31607683 = 31608506
877 + 31607629 = 31608506
907 + 31607599 = 31608506

Showing the first eight; more decompositions exist.
