Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460374, here are decompositions:

5 + 31460369 = 31460374
53 + 31460321 = 31460374
83 + 31460291 = 31460374
107 + 31460267 = 31460374
311 + 31460063 = 31460374
443 + 31459931 = 31460374
521 + 31459853 = 31460374
641 + 31459733 = 31460374

Showing the first eight; more decompositions exist.
