Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608694, here are decompositions:

107 + 31608587 = 31608694
167 + 31608527 = 31608694
197 + 31608497 = 31608694
353 + 31608341 = 31608694
431 + 31608263 = 31608694
563 + 31608131 = 31608694
587 + 31608107 = 31608694
647 + 31608047 = 31608694

Showing the first eight; more decompositions exist.
