Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556702, here are decompositions:

223 + 31556479 = 31556702
241 + 31556461 = 31556702
313 + 31556389 = 31556702
349 + 31556353 = 31556702
379 + 31556323 = 31556702
409 + 31556293 = 31556702
691 + 31556011 = 31556702
733 + 31555969 = 31556702

Showing the first eight; more decompositions exist.
