Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72710, here are decompositions:

3 + 72707 = 72710
31 + 72679 = 72710
37 + 72673 = 72710
61 + 72649 = 72710
67 + 72643 = 72710
97 + 72613 = 72710
151 + 72559 = 72710
163 + 72547 = 72710

Showing the first eight; more decompositions exist.
