Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608106, here are decompositions:

59 + 31608047 = 31608106
137 + 31607969 = 31608106
197 + 31607909 = 31608106
239 + 31607867 = 31608106
317 + 31607789 = 31608106
359 + 31607747 = 31608106
389 + 31607717 = 31608106
419 + 31607687 = 31608106

Showing the first eight; more decompositions exist.
