Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606104, here are decompositions:

7 + 31606097 = 31606104
17 + 31606087 = 31606104
37 + 31606067 = 31606104
43 + 31606061 = 31606104
53 + 31606051 = 31606104
151 + 31605953 = 31606104
191 + 31605913 = 31606104
227 + 31605877 = 31606104

Showing the first eight; more decompositions exist.
