Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584546, here are decompositions:

5 + 31584541 = 31584546
23 + 31584523 = 31584546
47 + 31584499 = 31584546
89 + 31584457 = 31584546
107 + 31584439 = 31584546
139 + 31584407 = 31584546
157 + 31584389 = 31584546
163 + 31584383 = 31584546

Showing the first eight; more decompositions exist.
