Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608104, here are decompositions:

13 + 31608091 = 31608104
37 + 31608067 = 31608104
43 + 31608061 = 31608104
67 + 31608037 = 31608104
313 + 31607791 = 31608104
421 + 31607683 = 31608104
433 + 31607671 = 31608104
523 + 31607581 = 31608104

Showing the first eight; more decompositions exist.
