Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464650, here are decompositions:

31 + 31464619 = 31464650
73 + 31464577 = 31464650
79 + 31464571 = 31464650
103 + 31464547 = 31464650
157 + 31464493 = 31464650
199 + 31464451 = 31464650
211 + 31464439 = 31464650
223 + 31464427 = 31464650

Showing the first eight; more decompositions exist.
