Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606106, here are decompositions:

19 + 31606087 = 31606106
193 + 31605913 = 31606106
229 + 31605877 = 31606106
283 + 31605823 = 31606106
349 + 31605757 = 31606106
379 + 31605727 = 31606106
409 + 31605697 = 31606106
487 + 31605619 = 31606106

Showing the first eight; more decompositions exist.
