Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567854, here are decompositions:

5 + 31567849 = 31567854
41 + 31567813 = 31567854
113 + 31567741 = 31567854
137 + 31567717 = 31567854
167 + 31567687 = 31567854
173 + 31567681 = 31567854
181 + 31567673 = 31567854
211 + 31567643 = 31567854

Showing the first eight; more decompositions exist.
