Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72266, here are decompositions:

13 + 72253 = 72266
37 + 72229 = 72266
43 + 72223 = 72266
97 + 72169 = 72266
127 + 72139 = 72266
157 + 72109 = 72266
163 + 72103 = 72266
193 + 72073 = 72266

Showing the first eight; more decompositions exist.
