Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64912, here are decompositions:

11 + 64901 = 64912
41 + 64871 = 64912
59 + 64853 = 64912
101 + 64811 = 64912
131 + 64781 = 64912
149 + 64763 = 64912
233 + 64679 = 64912
251 + 64661 = 64912

Showing the first eight; more decompositions exist.
