Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460560, here are decompositions:

11 + 31460549 = 31460560
23 + 31460537 = 31460560
191 + 31460369 = 31460560
239 + 31460321 = 31460560
269 + 31460291 = 31460560
281 + 31460279 = 31460560
293 + 31460267 = 31460560
431 + 31460129 = 31460560

Showing the first eight; more decompositions exist.
