Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619950, here are decompositions:

7 + 8619943 = 8619950
13 + 8619937 = 8619950
67 + 8619883 = 8619950
139 + 8619811 = 8619950
349 + 8619601 = 8619950
439 + 8619511 = 8619950
523 + 8619427 = 8619950
607 + 8619343 = 8619950

Showing the first eight; more decompositions exist.
