Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761812, here are decompositions:

5 + 8761807 = 8761812
23 + 8761789 = 8761812
61 + 8761751 = 8761812
79 + 8761733 = 8761812
109 + 8761703 = 8761812
173 + 8761639 = 8761812
179 + 8761633 = 8761812
181 + 8761631 = 8761812

Showing the first eight; more decompositions exist.
