Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72212, here are decompositions:

43 + 72169 = 72212
73 + 72139 = 72212
103 + 72109 = 72212
109 + 72103 = 72212
139 + 72073 = 72212
181 + 72031 = 72212
193 + 72019 = 72212
229 + 71983 = 72212

Showing the first eight; more decompositions exist.
