Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460176, here are decompositions:

3 + 31460173 = 31460176
47 + 31460129 = 31460176
113 + 31460063 = 31460176
227 + 31459949 = 31460176
239 + 31459937 = 31460176
317 + 31459859 = 31460176
347 + 31459829 = 31460176
443 + 31459733 = 31460176

Showing the first eight; more decompositions exist.
