Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620418, here are decompositions:

151 + 8620267 = 8620418
199 + 8620219 = 8620418
229 + 8620189 = 8620418
277 + 8620141 = 8620418
307 + 8620111 = 8620418
349 + 8620069 = 8620418
421 + 8619997 = 8620418
601 + 8619817 = 8620418

Showing the first eight; more decompositions exist.
