Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89072, here are decompositions:

3 + 89069 = 89072
31 + 89041 = 89072
79 + 88993 = 89072
103 + 88969 = 89072
199 + 88873 = 89072
211 + 88861 = 89072
229 + 88843 = 89072
271 + 88801 = 89072

Showing the first eight; more decompositions exist.
