Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498294, here are decompositions:

5 + 31498289 = 31498294
17 + 31498277 = 31498294
41 + 31498253 = 31498294
101 + 31498193 = 31498294
251 + 31498043 = 31498294
353 + 31497941 = 31498294
431 + 31497863 = 31498294
467 + 31497827 = 31498294

Showing the first eight; more decompositions exist.
