Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608622, here are decompositions:

173 + 31608449 = 31608622
281 + 31608341 = 31608622
359 + 31608263 = 31608622
491 + 31608131 = 31608622
593 + 31608029 = 31608622
653 + 31607969 = 31608622
701 + 31607921 = 31608622
719 + 31607903 = 31608622

Showing the first eight; more decompositions exist.
