Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619906, here are decompositions:

13 + 8619893 = 8619906
23 + 8619883 = 8619906
37 + 8619869 = 8619906
47 + 8619859 = 8619906
89 + 8619817 = 8619906
109 + 8619797 = 8619906
193 + 8619713 = 8619906
223 + 8619683 = 8619906

Showing the first eight; more decompositions exist.
