Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72356, here are decompositions:

3 + 72353 = 72356
19 + 72337 = 72356
43 + 72313 = 72356
79 + 72277 = 72356
103 + 72253 = 72356
127 + 72229 = 72356
283 + 72073 = 72356
313 + 72043 = 72356

Showing the first eight; more decompositions exist.
