Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72206, here are decompositions:

37 + 72169 = 72206
67 + 72139 = 72206
97 + 72109 = 72206
103 + 72103 = 72206
163 + 72043 = 72206
223 + 71983 = 72206
307 + 71899 = 72206
397 + 71809 = 72206

Showing the first eight; more decompositions exist.
