Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620312, here are decompositions:

5 + 8620307 = 8620312
23 + 8620289 = 8620312
53 + 8620259 = 8620312
101 + 8620211 = 8620312
179 + 8620133 = 8620312
191 + 8620121 = 8620312
263 + 8620049 = 8620312
269 + 8620043 = 8620312

Showing the first eight; more decompositions exist.
