Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72682, here are decompositions:

3 + 72679 = 72682
11 + 72671 = 72682
59 + 72623 = 72682
131 + 72551 = 72682
149 + 72533 = 72682
179 + 72503 = 72682
251 + 72431 = 72682
431 + 72251 = 72682

Showing the first eight; more decompositions exist.
