Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533486, here are decompositions:

37 + 31533449 = 31533486
73 + 31533413 = 31533486
97 + 31533389 = 31533486
107 + 31533379 = 31533486
227 + 31533259 = 31533486
277 + 31533209 = 31533486
337 + 31533149 = 31533486
353 + 31533133 = 31533486

Showing the first eight; more decompositions exist.
