Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498276, here are decompositions:

3 + 31498273 = 31498276
23 + 31498253 = 31498276
59 + 31498217 = 31498276
83 + 31498193 = 31498276
233 + 31498043 = 31498276
269 + 31498007 = 31498276
347 + 31497929 = 31498276
449 + 31497827 = 31498276

Showing the first eight; more decompositions exist.
