Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498452, here are decompositions:

31 + 31498421 = 31498452
103 + 31498349 = 31498452
109 + 31498343 = 31498452
163 + 31498289 = 31498452
173 + 31498279 = 31498452
179 + 31498273 = 31498452
199 + 31498253 = 31498452
239 + 31498213 = 31498452

Showing the first eight; more decompositions exist.
