Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64380, here are decompositions:

7 + 64373 = 64380
47 + 64333 = 64380
53 + 64327 = 64380
61 + 64319 = 64380
79 + 64301 = 64380
97 + 64283 = 64380
101 + 64279 = 64380
109 + 64271 = 64380

Showing the first eight; more decompositions exist.
