Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567552, here are decompositions:

41 + 31567511 = 31567552
101 + 31567451 = 31567552
239 + 31567313 = 31567552
281 + 31567271 = 31567552
311 + 31567241 = 31567552
461 + 31567091 = 31567552
503 + 31567049 = 31567552
509 + 31567043 = 31567552

Showing the first eight; more decompositions exist.
