Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498282, here are decompositions:

3 + 31498279 = 31498282
5 + 31498277 = 31498282
29 + 31498253 = 31498282
83 + 31498199 = 31498282
89 + 31498193 = 31498282
131 + 31498151 = 31498282
239 + 31498043 = 31498282
353 + 31497929 = 31498282

Showing the first eight; more decompositions exist.
