Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464458, here are decompositions:

7 + 31464451 = 31464458
19 + 31464439 = 31464458
31 + 31464427 = 31464458
37 + 31464421 = 31464458
61 + 31464397 = 31464458
271 + 31464187 = 31464458
379 + 31464079 = 31464458
397 + 31464061 = 31464458

Showing the first eight; more decompositions exist.
