Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610136, here are decompositions:

23 + 31610113 = 31610136
29 + 31610107 = 31610136
43 + 31610093 = 31610136
53 + 31610083 = 31610136
73 + 31610063 = 31610136
97 + 31610039 = 31610136
113 + 31610023 = 31610136
127 + 31610009 = 31610136

Showing the first eight; more decompositions exist.
