Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567834, here are decompositions:

191 + 31567643 = 31567834
197 + 31567637 = 31567834
281 + 31567553 = 31567834
383 + 31567451 = 31567834
521 + 31567313 = 31567834
563 + 31567271 = 31567834
593 + 31567241 = 31567834
677 + 31567157 = 31567834

Showing the first eight; more decompositions exist.
