Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64870, here are decompositions:

17 + 64853 = 64870
53 + 64817 = 64870
59 + 64811 = 64870
89 + 64781 = 64870
107 + 64763 = 64870
191 + 64679 = 64870
257 + 64613 = 64870
269 + 64601 = 64870

Showing the first eight; more decompositions exist.
