Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72708, here are decompositions:

7 + 72701 = 72708
19 + 72689 = 72708
29 + 72679 = 72708
37 + 72671 = 72708
47 + 72661 = 72708
59 + 72649 = 72708
61 + 72647 = 72708
131 + 72577 = 72708

Showing the first eight; more decompositions exist.
