Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73438, here are decompositions:

5 + 73433 = 73438
17 + 73421 = 73438
59 + 73379 = 73438
107 + 73331 = 73438
179 + 73259 = 73438
257 + 73181 = 73438
311 + 73127 = 73438
317 + 73121 = 73438

Showing the first eight; more decompositions exist.
