Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72416, here are decompositions:

37 + 72379 = 72416
79 + 72337 = 72416
103 + 72313 = 72416
109 + 72307 = 72416
139 + 72277 = 72416
163 + 72253 = 72416
193 + 72223 = 72416
277 + 72139 = 72416

Showing the first eight; more decompositions exist.
