Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619944, here are decompositions:

7 + 8619937 = 8619944
61 + 8619883 = 8619944
127 + 8619817 = 8619944
283 + 8619661 = 8619944
433 + 8619511 = 8619944
523 + 8619421 = 8619944
547 + 8619397 = 8619944
601 + 8619343 = 8619944

Showing the first eight; more decompositions exist.
