Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460044, here are decompositions:

107 + 31459937 = 31460044
113 + 31459931 = 31460044
191 + 31459853 = 31460044
197 + 31459847 = 31460044
311 + 31459733 = 31460044
347 + 31459697 = 31460044
383 + 31459661 = 31460044
491 + 31459553 = 31460044

Showing the first eight; more decompositions exist.
