Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460568, here are decompositions:

17 + 31460551 = 31460568
19 + 31460549 = 31460568
31 + 31460537 = 31460568
59 + 31460509 = 31460568
71 + 31460497 = 31460568
127 + 31460441 = 31460568
137 + 31460431 = 31460568
199 + 31460369 = 31460568

Showing the first eight; more decompositions exist.
