Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64688, here are decompositions:

61 + 64627 = 64688
67 + 64621 = 64688
79 + 64609 = 64688
97 + 64591 = 64688
109 + 64579 = 64688
199 + 64489 = 64688
307 + 64381 = 64688
409 + 64279 = 64688

Showing the first eight; more decompositions exist.
