Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72722, here are decompositions:

3 + 72719 = 72722
43 + 72679 = 72722
61 + 72661 = 72722
73 + 72649 = 72722
79 + 72643 = 72722
109 + 72613 = 72722
163 + 72559 = 72722
229 + 72493 = 72722

Showing the first eight; more decompositions exist.
