Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85042, here are decompositions:

5 + 85037 = 85042
173 + 84869 = 85042
233 + 84809 = 85042
281 + 84761 = 85042
311 + 84731 = 85042
383 + 84659 = 85042
389 + 84653 = 85042
491 + 84551 = 85042

Showing the first eight; more decompositions exist.
