Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460008, here are decompositions:

59 + 31459949 = 31460008
71 + 31459937 = 31460008
149 + 31459859 = 31460008
179 + 31459829 = 31460008
311 + 31459697 = 31460008
347 + 31459661 = 31460008
389 + 31459619 = 31460008
467 + 31459541 = 31460008

Showing the first eight; more decompositions exist.
