Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621852, here are decompositions:

73 + 8621779 = 8621852
79 + 8621773 = 8621852
103 + 8621749 = 8621852
199 + 8621653 = 8621852
229 + 8621623 = 8621852
271 + 8621581 = 8621852
373 + 8621479 = 8621852
409 + 8621443 = 8621852

Showing the first eight; more decompositions exist.
