Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460378, here are decompositions:

31 + 31460347 = 31460378
97 + 31460281 = 31460378
181 + 31460197 = 31460378
211 + 31460167 = 31460378
241 + 31460137 = 31460378
379 + 31459999 = 31460378
487 + 31459891 = 31460378
571 + 31459807 = 31460378

Showing the first eight; more decompositions exist.
