Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85586, here are decompositions:

37 + 85549 = 85586
73 + 85513 = 85586
139 + 85447 = 85586
157 + 85429 = 85586
223 + 85363 = 85586
283 + 85303 = 85586
349 + 85237 = 85586
373 + 85213 = 85586

Showing the first eight; more decompositions exist.
