Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734420, here are decompositions:

3 + 8734417 = 8734420
17 + 8734403 = 8734420
47 + 8734373 = 8734420
53 + 8734367 = 8734420
59 + 8734361 = 8734420
137 + 8734283 = 8734420
173 + 8734247 = 8734420
197 + 8734223 = 8734420

Showing the first eight; more decompositions exist.
