Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85242, here are decompositions:

5 + 85237 = 85242
13 + 85229 = 85242
19 + 85223 = 85242
29 + 85213 = 85242
41 + 85201 = 85242
43 + 85199 = 85242
83 + 85159 = 85242
109 + 85133 = 85242

Showing the first eight; more decompositions exist.
