Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556654, here are decompositions:

7 + 31556647 = 31556654
97 + 31556557 = 31556654
193 + 31556461 = 31556654
313 + 31556341 = 31556654
331 + 31556323 = 31556654
541 + 31556113 = 31556654
643 + 31556011 = 31556654
673 + 31555981 = 31556654

Showing the first eight; more decompositions exist.
