Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608670, here are decompositions:

3 + 31608667 = 31608670
83 + 31608587 = 31608670
173 + 31608497 = 31608670
503 + 31608167 = 31608670
521 + 31608149 = 31608670
563 + 31608107 = 31608670
641 + 31608029 = 31608670
701 + 31607969 = 31608670

Showing the first eight; more decompositions exist.
