Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64284, here are decompositions:

5 + 64279 = 64284
13 + 64271 = 64284
47 + 64237 = 64284
53 + 64231 = 64284
61 + 64223 = 64284
67 + 64217 = 64284
97 + 64187 = 64284
113 + 64171 = 64284

Showing the first eight; more decompositions exist.
