Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72908, here are decompositions:

7 + 72901 = 72908
19 + 72889 = 72908
37 + 72871 = 72908
181 + 72727 = 72908
229 + 72679 = 72908
331 + 72577 = 72908
349 + 72559 = 72908
439 + 72469 = 72908

Showing the first eight; more decompositions exist.
