Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734720, here are decompositions:

23 + 8734697 = 8734720
107 + 8734613 = 8734720
149 + 8734571 = 8734720
251 + 8734469 = 8734720
317 + 8734403 = 8734720
347 + 8734373 = 8734720
353 + 8734367 = 8734720
359 + 8734361 = 8734720

Showing the first eight; more decompositions exist.
