Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741620, here are decompositions:

11 + 8741609 = 8741620
149 + 8741471 = 8741620
227 + 8741393 = 8741620
257 + 8741363 = 8741620
311 + 8741309 = 8741620
317 + 8741303 = 8741620
389 + 8741231 = 8741620
467 + 8741153 = 8741620

Showing the first eight; more decompositions exist.
