Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535974, here are decompositions:

227 + 31535747 = 31535974
233 + 31535741 = 31535974
257 + 31535717 = 31535974
293 + 31535681 = 31535974
317 + 31535657 = 31535974
383 + 31535591 = 31535974
557 + 31535417 = 31535974
563 + 31535411 = 31535974

Showing the first eight; more decompositions exist.
