Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536166, here are decompositions:

5 + 31536161 = 31536166
113 + 31536053 = 31536166
149 + 31536017 = 31536166
227 + 31535939 = 31536166
257 + 31535909 = 31536166
419 + 31535747 = 31536166
449 + 31535717 = 31536166
509 + 31535657 = 31536166

Showing the first eight; more decompositions exist.
