Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556774, here are decompositions:

3 + 31556771 = 31556774
37 + 31556737 = 31556774
127 + 31556647 = 31556774
307 + 31556467 = 31556774
313 + 31556461 = 31556774
367 + 31556407 = 31556774
421 + 31556353 = 31556774
433 + 31556341 = 31556774

Showing the first eight; more decompositions exist.
