Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80072, here are decompositions:

73 + 79999 = 80072
199 + 79873 = 80072
211 + 79861 = 80072
229 + 79843 = 80072
271 + 79801 = 80072
373 + 79699 = 80072
379 + 79693 = 80072
439 + 79633 = 80072

Showing the first eight; more decompositions exist.
