Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618482, here are decompositions:

19 + 31618463 = 31618482
41 + 31618441 = 31618482
59 + 31618423 = 31618482
73 + 31618409 = 31618482
79 + 31618403 = 31618482
163 + 31618319 = 31618482
193 + 31618289 = 31618482
251 + 31618231 = 31618482

Showing the first eight; more decompositions exist.
