Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567426, here are decompositions:

29 + 31567397 = 31567426
113 + 31567313 = 31567426
269 + 31567157 = 31567426
383 + 31567043 = 31567426
563 + 31566863 = 31567426
587 + 31566839 = 31567426
599 + 31566827 = 31567426
677 + 31566749 = 31567426

Showing the first eight; more decompositions exist.
