Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567522, here are decompositions:

11 + 31567511 = 31567522
71 + 31567451 = 31567522
251 + 31567271 = 31567522
281 + 31567241 = 31567522
431 + 31567091 = 31567522
479 + 31567043 = 31567522
659 + 31566863 = 31567522
683 + 31566839 = 31567522

Showing the first eight; more decompositions exist.
