Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567794, here are decompositions:

53 + 31567741 = 31567794
101 + 31567693 = 31567794
107 + 31567687 = 31567794
113 + 31567681 = 31567794
151 + 31567643 = 31567794
157 + 31567637 = 31567794
173 + 31567621 = 31567794
191 + 31567603 = 31567794

Showing the first eight; more decompositions exist.
