Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72772, here are decompositions:

5 + 72767 = 72772
53 + 72719 = 72772
71 + 72701 = 72772
83 + 72689 = 72772
101 + 72671 = 72772
149 + 72623 = 72772
239 + 72533 = 72772
269 + 72503 = 72772

Showing the first eight; more decompositions exist.
