Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761830, here are decompositions:

23 + 8761807 = 8761830
41 + 8761789 = 8761830
67 + 8761763 = 8761830
79 + 8761751 = 8761830
97 + 8761733 = 8761830
109 + 8761721 = 8761830
127 + 8761703 = 8761830
139 + 8761691 = 8761830

Showing the first eight; more decompositions exist.
