Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85886, here are decompositions:

43 + 85843 = 85886
67 + 85819 = 85886
337 + 85549 = 85886
373 + 85513 = 85886
433 + 85453 = 85886
439 + 85447 = 85886
457 + 85429 = 85886
523 + 85363 = 85886

Showing the first eight; more decompositions exist.
