Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73200, here are decompositions:

11 + 73189 = 73200
19 + 73181 = 73200
59 + 73141 = 73200
67 + 73133 = 73200
73 + 73127 = 73200
79 + 73121 = 73200
109 + 73091 = 73200
137 + 73063 = 73200

Showing the first eight; more decompositions exist.
