Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619900, here are decompositions:

7 + 8619893 = 8619900
17 + 8619883 = 8619900
31 + 8619869 = 8619900
41 + 8619859 = 8619900
43 + 8619857 = 8619900
83 + 8619817 = 8619900
89 + 8619811 = 8619900
103 + 8619797 = 8619900

Showing the first eight; more decompositions exist.
