Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460140, here are decompositions:

3 + 31460137 = 31460140
11 + 31460129 = 31460140
191 + 31459949 = 31460140
281 + 31459859 = 31460140
293 + 31459847 = 31460140
311 + 31459829 = 31460140
431 + 31459709 = 31460140
443 + 31459697 = 31460140

Showing the first eight; more decompositions exist.
