Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460476, here are decompositions:

107 + 31460369 = 31460476
137 + 31460339 = 31460476
197 + 31460279 = 31460476
347 + 31460129 = 31460476
617 + 31459859 = 31460476
647 + 31459829 = 31460476
743 + 31459733 = 31460476
797 + 31459679 = 31460476

Showing the first eight; more decompositions exist.
