Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516546, here are decompositions:

3 + 31516543 = 31516546
23 + 31516523 = 31516546
53 + 31516493 = 31516546
167 + 31516379 = 31516546
227 + 31516319 = 31516546
293 + 31516253 = 31516546
389 + 31516157 = 31516546
443 + 31516103 = 31516546

Showing the first eight; more decompositions exist.
