Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464758, here are decompositions:

109 + 31464649 = 31464758
139 + 31464619 = 31464758
181 + 31464577 = 31464758
211 + 31464547 = 31464758
277 + 31464481 = 31464758
307 + 31464451 = 31464758
331 + 31464427 = 31464758
337 + 31464421 = 31464758

Showing the first eight; more decompositions exist.
