Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608874, here are decompositions:

23 + 31608851 = 31608874
53 + 31608821 = 31608874
137 + 31608737 = 31608874
347 + 31608527 = 31608874
743 + 31608131 = 31608874
827 + 31608047 = 31608874
953 + 31607921 = 31608874
971 + 31607903 = 31608874

Showing the first eight; more decompositions exist.
