Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72208, here are decompositions:

41 + 72167 = 72208
47 + 72161 = 72208
107 + 72101 = 72208
131 + 72077 = 72208
347 + 71861 = 72208
359 + 71849 = 72208
401 + 71807 = 72208
419 + 71789 = 72208

Showing the first eight; more decompositions exist.
