Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536366, here are decompositions:

5 + 31536361 = 31536366
7 + 31536359 = 31536366
13 + 31536353 = 31536366
19 + 31536347 = 31536366
53 + 31536313 = 31536366
73 + 31536293 = 31536366
79 + 31536287 = 31536366
139 + 31536227 = 31536366

Showing the first eight; more decompositions exist.
