Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536018, here are decompositions:

37 + 31535981 = 31536018
71 + 31535947 = 31536018
79 + 31535939 = 31536018
109 + 31535909 = 31536018
139 + 31535879 = 31536018
191 + 31535827 = 31536018
197 + 31535821 = 31536018
271 + 31535747 = 31536018

Showing the first eight; more decompositions exist.
