Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89078, here are decompositions:

7 + 89071 = 89078
37 + 89041 = 89078
61 + 89017 = 89078
109 + 88969 = 89078
127 + 88951 = 89078
181 + 88897 = 89078
211 + 88867 = 89078
271 + 88807 = 89078

Showing the first eight; more decompositions exist.
