Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72210, here are decompositions:

37 + 72173 = 72210
41 + 72169 = 72210
43 + 72167 = 72210
71 + 72139 = 72210
101 + 72109 = 72210
107 + 72103 = 72210
109 + 72101 = 72210
137 + 72073 = 72210

Showing the first eight; more decompositions exist.
