Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64878, here are decompositions:

7 + 64871 = 64878
29 + 64849 = 64878
61 + 64817 = 64878
67 + 64811 = 64878
97 + 64781 = 64878
131 + 64747 = 64878
199 + 64679 = 64878
211 + 64667 = 64878

Showing the first eight; more decompositions exist.
