Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460148, here are decompositions:

11 + 31460137 = 31460148
19 + 31460129 = 31460148
131 + 31460017 = 31460148
149 + 31459999 = 31460148
199 + 31459949 = 31460148
211 + 31459937 = 31460148
257 + 31459891 = 31460148
389 + 31459759 = 31460148

Showing the first eight; more decompositions exist.
