Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464492, here are decompositions:

11 + 31464481 = 31464492
29 + 31464463 = 31464492
41 + 31464451 = 31464492
53 + 31464439 = 31464492
71 + 31464421 = 31464492
83 + 31464409 = 31464492
151 + 31464341 = 31464492
211 + 31464281 = 31464492

Showing the first eight; more decompositions exist.
