Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536698, here are decompositions:

199 + 31536499 = 31536698
307 + 31536391 = 31536698
337 + 31536361 = 31536698
601 + 31536097 = 31536698
751 + 31535947 = 31536698
757 + 31535941 = 31536698
877 + 31535821 = 31536698
1231 + 31535467 = 31536698

Showing the first eight; more decompositions exist.
