Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72308, here are decompositions:

31 + 72277 = 72308
37 + 72271 = 72308
79 + 72229 = 72308
97 + 72211 = 72308
139 + 72169 = 72308
199 + 72109 = 72308
277 + 72031 = 72308
337 + 71971 = 72308

Showing the first eight; more decompositions exist.
