Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72764, here are decompositions:

31 + 72733 = 72764
37 + 72727 = 72764
103 + 72661 = 72764
151 + 72613 = 72764
271 + 72493 = 72764
283 + 72481 = 72764
397 + 72367 = 72764
457 + 72307 = 72764

Showing the first eight; more decompositions exist.
