Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464764, here are decompositions:

7 + 31464757 = 31464764
193 + 31464571 = 31464764
271 + 31464493 = 31464764
283 + 31464481 = 31464764
313 + 31464451 = 31464764
337 + 31464427 = 31464764
367 + 31464397 = 31464764
571 + 31464193 = 31464764

Showing the first eight; more decompositions exist.
