Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473546, here are decompositions:

17 + 31473529 = 31473546
23 + 31473523 = 31473546
59 + 31473487 = 31473546
67 + 31473479 = 31473546
89 + 31473457 = 31473546
109 + 31473437 = 31473546
149 + 31473397 = 31473546
233 + 31473313 = 31473546

Showing the first eight; more decompositions exist.
