Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536196, here are decompositions:

179 + 31536017 = 31536196
257 + 31535939 = 31536196
317 + 31535879 = 31536196
443 + 31535753 = 31536196
449 + 31535747 = 31536196
479 + 31535717 = 31536196
557 + 31535639 = 31536196
563 + 31535633 = 31536196

Showing the first eight; more decompositions exist.
