Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85260, here are decompositions:

13 + 85247 = 85260
17 + 85243 = 85260
23 + 85237 = 85260
31 + 85229 = 85260
37 + 85223 = 85260
47 + 85213 = 85260
59 + 85201 = 85260
61 + 85199 = 85260

Showing the first eight; more decompositions exist.
