Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498326, here are decompositions:

19 + 31498307 = 31498326
37 + 31498289 = 31498326
47 + 31498279 = 31498326
53 + 31498273 = 31498326
73 + 31498253 = 31498326
109 + 31498217 = 31498326
113 + 31498213 = 31498326
127 + 31498199 = 31498326

Showing the first eight; more decompositions exist.
