Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73420, here are decompositions:

3 + 73417 = 73420
41 + 73379 = 73420
59 + 73361 = 73420
89 + 73331 = 73420
239 + 73181 = 73420
293 + 73127 = 73420
359 + 73061 = 73420
383 + 73037 = 73420

Showing the first eight; more decompositions exist.
