Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468498, here are decompositions:

101 + 31468397 = 31468498
107 + 31468391 = 31468498
167 + 31468331 = 31468498
179 + 31468319 = 31468498
227 + 31468271 = 31468498
239 + 31468259 = 31468498
251 + 31468247 = 31468498
401 + 31468097 = 31468498

Showing the first eight; more decompositions exist.
