Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524546, here are decompositions:

5 + 31524541 = 31524546
13 + 31524533 = 31524546
23 + 31524523 = 31524546
29 + 31524517 = 31524546
37 + 31524509 = 31524546
47 + 31524499 = 31524546
127 + 31524419 = 31524546
269 + 31524277 = 31524546

Showing the first eight; more decompositions exist.
