Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567474, here are decompositions:

23 + 31567451 = 31567474
47 + 31567427 = 31567474
233 + 31567241 = 31567474
317 + 31567157 = 31567474
383 + 31567091 = 31567474
431 + 31567043 = 31567474
563 + 31566911 = 31567474
647 + 31566827 = 31567474

Showing the first eight; more decompositions exist.
