Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556534, here are decompositions:

67 + 31556467 = 31556534
73 + 31556461 = 31556534
127 + 31556407 = 31556534
181 + 31556353 = 31556534
193 + 31556341 = 31556534
211 + 31556323 = 31556534
241 + 31556293 = 31556534
421 + 31556113 = 31556534

Showing the first eight; more decompositions exist.
