Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72850, here are decompositions:

53 + 72797 = 72850
83 + 72767 = 72850
131 + 72719 = 72850
149 + 72701 = 72850
179 + 72671 = 72850
227 + 72623 = 72850
233 + 72617 = 72850
317 + 72533 = 72850

Showing the first eight; more decompositions exist.
