Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486326, here are decompositions:

19 + 31486307 = 31486326
23 + 31486303 = 31486326
37 + 31486289 = 31486326
43 + 31486283 = 31486326
59 + 31486267 = 31486326
73 + 31486253 = 31486326
97 + 31486229 = 31486326
163 + 31486163 = 31486326

Showing the first eight; more decompositions exist.
