Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619546, here are decompositions:

3 + 31619543 = 31619546
19 + 31619527 = 31619546
37 + 31619509 = 31619546
139 + 31619407 = 31619546
157 + 31619389 = 31619546
337 + 31619209 = 31619546
367 + 31619179 = 31619546
547 + 31618999 = 31619546

Showing the first eight; more decompositions exist.
