Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460662, here are decompositions:

5 + 31460657 = 31460662
53 + 31460609 = 31460662
113 + 31460549 = 31460662
179 + 31460483 = 31460662
263 + 31460399 = 31460662
293 + 31460369 = 31460662
383 + 31460279 = 31460662
599 + 31460063 = 31460662

Showing the first eight; more decompositions exist.
