Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536098, here are decompositions:

37 + 31536061 = 31536098
79 + 31536019 = 31536098
151 + 31535947 = 31536098
157 + 31535941 = 31536098
271 + 31535827 = 31536098
277 + 31535821 = 31536098
547 + 31535551 = 31536098
631 + 31535467 = 31536098

Showing the first eight; more decompositions exist.
