Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83072, here are decompositions:

13 + 83059 = 83072
109 + 82963 = 83072
181 + 82891 = 83072
313 + 82759 = 83072
349 + 82723 = 83072
373 + 82699 = 83072
421 + 82651 = 83072
439 + 82633 = 83072

Showing the first eight; more decompositions exist.
