Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556834, here are decompositions:

7 + 31556827 = 31556834
31 + 31556803 = 31556834
97 + 31556737 = 31556834
181 + 31556653 = 31556834
277 + 31556557 = 31556834
367 + 31556467 = 31556834
373 + 31556461 = 31556834
541 + 31556293 = 31556834

Showing the first eight; more decompositions exist.
