Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536898, here are decompositions:

167 + 31536731 = 31536898
179 + 31536719 = 31536898
191 + 31536707 = 31536898
269 + 31536629 = 31536898
347 + 31536551 = 31536898
359 + 31536539 = 31536898
797 + 31536101 = 31536898
881 + 31536017 = 31536898

Showing the first eight; more decompositions exist.
