Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567954, here are decompositions:

23 + 31567931 = 31567954
71 + 31567883 = 31567954
281 + 31567673 = 31567954
311 + 31567643 = 31567954
317 + 31567637 = 31567954
401 + 31567553 = 31567954
443 + 31567511 = 31567954
503 + 31567451 = 31567954

Showing the first eight; more decompositions exist.
