Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464522, here are decompositions:

13 + 31464509 = 31464522
29 + 31464493 = 31464522
41 + 31464481 = 31464522
59 + 31464463 = 31464522
71 + 31464451 = 31464522
79 + 31464443 = 31464522
83 + 31464439 = 31464522
101 + 31464421 = 31464522

Showing the first eight; more decompositions exist.
