Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78284, here are decompositions:

7 + 78277 = 78284
43 + 78241 = 78284
127 + 78157 = 78284
163 + 78121 = 78284
277 + 78007 = 78284
307 + 77977 = 78284
421 + 77863 = 78284
487 + 77797 = 78284

Showing the first eight; more decompositions exist.
