Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556546, here are decompositions:

67 + 31556479 = 31556546
79 + 31556467 = 31556546
139 + 31556407 = 31556546
157 + 31556389 = 31556546
193 + 31556353 = 31556546
223 + 31556323 = 31556546
397 + 31556149 = 31556546
433 + 31556113 = 31556546

Showing the first eight; more decompositions exist.
