Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567546, here are decompositions:

149 + 31567397 = 31567546
233 + 31567313 = 31567546
389 + 31567157 = 31567546
503 + 31567043 = 31567546
683 + 31566863 = 31567546
719 + 31566827 = 31567546
743 + 31566803 = 31567546
797 + 31566749 = 31567546

Showing the first eight; more decompositions exist.
