Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519326, here are decompositions:

5 + 31519321 = 31519326
19 + 31519307 = 31519326
29 + 31519297 = 31519326
37 + 31519289 = 31519326
73 + 31519253 = 31519326
79 + 31519247 = 31519326
127 + 31519199 = 31519326
227 + 31519099 = 31519326

Showing the first eight; more decompositions exist.
