Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460060, here are decompositions:

7 + 31460053 = 31460060
43 + 31460017 = 31460060
61 + 31459999 = 31460060
67 + 31459993 = 31460060
97 + 31459963 = 31460060
211 + 31459849 = 31460060
337 + 31459723 = 31460060
409 + 31459651 = 31460060

Showing the first eight; more decompositions exist.
