Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460194, here are decompositions:

131 + 31460063 = 31460194
257 + 31459937 = 31460194
263 + 31459931 = 31460194
347 + 31459847 = 31460194
461 + 31459733 = 31460194
641 + 31459553 = 31460194
653 + 31459541 = 31460194
677 + 31459517 = 31460194

Showing the first eight; more decompositions exist.
