Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64820, here are decompositions:

3 + 64817 = 64820
37 + 64783 = 64820
73 + 64747 = 64820
103 + 64717 = 64820
127 + 64693 = 64820
157 + 64663 = 64820
193 + 64627 = 64820
199 + 64621 = 64820

Showing the first eight; more decompositions exist.
