Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536244, here are decompositions:

17 + 31536227 = 31536244
41 + 31536203 = 31536244
83 + 31536161 = 31536244
191 + 31536053 = 31536244
227 + 31536017 = 31536244
263 + 31535981 = 31536244
491 + 31535753 = 31536244
503 + 31535741 = 31536244

Showing the first eight; more decompositions exist.
