Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460564, here are decompositions:

13 + 31460551 = 31460564
67 + 31460497 = 31460564
73 + 31460491 = 31460564
151 + 31460413 = 31460564
271 + 31460293 = 31460564
283 + 31460281 = 31460564
367 + 31460197 = 31460564
397 + 31460167 = 31460564

Showing the first eight; more decompositions exist.
