Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460550, here are decompositions:

13 + 31460537 = 31460550
41 + 31460509 = 31460550
53 + 31460497 = 31460550
59 + 31460491 = 31460550
67 + 31460483 = 31460550
109 + 31460441 = 31460550
137 + 31460413 = 31460550
151 + 31460399 = 31460550

Showing the first eight; more decompositions exist.
