Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460548, here are decompositions:

11 + 31460537 = 31460548
107 + 31460441 = 31460548
149 + 31460399 = 31460548
179 + 31460369 = 31460548
227 + 31460321 = 31460548
257 + 31460291 = 31460548
269 + 31460279 = 31460548
281 + 31460267 = 31460548

Showing the first eight; more decompositions exist.
