Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621762, here are decompositions:

13 + 8621749 = 8621762
109 + 8621653 = 8621762
139 + 8621623 = 8621762
181 + 8621581 = 8621762
211 + 8621551 = 8621762
271 + 8621491 = 8621762
283 + 8621479 = 8621762
349 + 8621413 = 8621762

Showing the first eight; more decompositions exist.
