Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536186, here are decompositions:

89 + 31536097 = 31536186
137 + 31536049 = 31536186
167 + 31536019 = 31536186
239 + 31535947 = 31536186
277 + 31535909 = 31536186
307 + 31535879 = 31536186
359 + 31535827 = 31536186
389 + 31535797 = 31536186

Showing the first eight; more decompositions exist.
