Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620466, here are decompositions:

37 + 8620429 = 8620466
73 + 8620393 = 8620466
97 + 8620369 = 8620466
139 + 8620327 = 8620466
199 + 8620267 = 8620466
277 + 8620189 = 8620466
307 + 8620159 = 8620466
397 + 8620069 = 8620466

Showing the first eight; more decompositions exist.
