Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73290, here are decompositions:

13 + 73277 = 73290
31 + 73259 = 73290
47 + 73243 = 73290
53 + 73237 = 73290
101 + 73189 = 73290
109 + 73181 = 73290
149 + 73141 = 73290
157 + 73133 = 73290

Showing the first eight; more decompositions exist.
