Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64100, here are decompositions:

19 + 64081 = 64100
37 + 64063 = 64100
67 + 64033 = 64100
103 + 63997 = 64100
151 + 63949 = 64100
193 + 63907 = 64100
199 + 63901 = 64100
277 + 63823 = 64100

Showing the first eight; more decompositions exist.
