Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536958, here are decompositions:

41 + 31536917 = 31536958
137 + 31536821 = 31536958
227 + 31536731 = 31536958
239 + 31536719 = 31536958
251 + 31536707 = 31536958
419 + 31536539 = 31536958
599 + 31536359 = 31536958
797 + 31536161 = 31536958

Showing the first eight; more decompositions exist.
