Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718464, here are decompositions:

3 + 8718461 = 8718464
37 + 8718427 = 8718464
151 + 8718313 = 8718464
163 + 8718301 = 8718464
193 + 8718271 = 8718464
367 + 8718097 = 8718464
373 + 8718091 = 8718464
421 + 8718043 = 8718464

Showing the first eight; more decompositions exist.
