Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85284, here are decompositions:

37 + 85247 = 85284
41 + 85243 = 85284
47 + 85237 = 85284
61 + 85223 = 85284
71 + 85213 = 85284
83 + 85201 = 85284
137 + 85147 = 85284
151 + 85133 = 85284

Showing the first eight; more decompositions exist.
