Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620402, here are decompositions:

41 + 8620361 = 8620402
53 + 8620349 = 8620402
113 + 8620289 = 8620402
191 + 8620211 = 8620402
251 + 8620151 = 8620402
269 + 8620133 = 8620402
281 + 8620121 = 8620402
293 + 8620109 = 8620402

Showing the first eight; more decompositions exist.
