Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486498, here are decompositions:

5 + 31486493 = 31486498
41 + 31486457 = 31486498
47 + 31486451 = 31486498
107 + 31486391 = 31486498
149 + 31486349 = 31486498
191 + 31486307 = 31486498
227 + 31486271 = 31486498
269 + 31486229 = 31486498

Showing the first eight; more decompositions exist.
