Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64720, here are decompositions:

3 + 64717 = 64720
11 + 64709 = 64720
41 + 64679 = 64720
53 + 64667 = 64720
59 + 64661 = 64720
107 + 64613 = 64720
167 + 64553 = 64720
269 + 64451 = 64720

Showing the first eight; more decompositions exist.
