Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64974, here are decompositions:

5 + 64969 = 64974
23 + 64951 = 64974
37 + 64937 = 64974
47 + 64927 = 64974
53 + 64921 = 64974
73 + 64901 = 64974
83 + 64891 = 64974
97 + 64877 = 64974

Showing the first eight; more decompositions exist.
