Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85072, here are decompositions:

11 + 85061 = 85072
23 + 85049 = 85072
263 + 84809 = 85072
311 + 84761 = 85072
353 + 84719 = 85072
359 + 84713 = 85072
419 + 84653 = 85072
443 + 84629 = 85072

Showing the first eight; more decompositions exist.
