Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536188, here are decompositions:

127 + 31536061 = 31536188
139 + 31536049 = 31536188
241 + 31535947 = 31536188
367 + 31535821 = 31536188
379 + 31535809 = 31536188
769 + 31535419 = 31536188
811 + 31535377 = 31536188
877 + 31535311 = 31536188

Showing the first eight; more decompositions exist.
