Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498354, here are decompositions:

5 + 31498349 = 31498354
11 + 31498343 = 31498354
47 + 31498307 = 31498354
101 + 31498253 = 31498354
137 + 31498217 = 31498354
311 + 31498043 = 31498354
347 + 31498007 = 31498354
491 + 31497863 = 31498354

Showing the first eight; more decompositions exist.
