Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619930, here are decompositions:

37 + 8619893 = 8619930
47 + 8619883 = 8619930
61 + 8619869 = 8619930
71 + 8619859 = 8619930
73 + 8619857 = 8619930
113 + 8619817 = 8619930
139 + 8619791 = 8619930
157 + 8619773 = 8619930

Showing the first eight; more decompositions exist.
