Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72608, here are decompositions:

31 + 72577 = 72608
61 + 72547 = 72608
127 + 72481 = 72608
139 + 72469 = 72608
229 + 72379 = 72608
241 + 72367 = 72608
271 + 72337 = 72608
331 + 72277 = 72608

Showing the first eight; more decompositions exist.
