Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64890, here are decompositions:

11 + 64879 = 64890
13 + 64877 = 64890
19 + 64871 = 64890
37 + 64853 = 64890
41 + 64849 = 64890
73 + 64817 = 64890
79 + 64811 = 64890
97 + 64793 = 64890

Showing the first eight; more decompositions exist.
