Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636780, here are decompositions:

43 + 8636737 = 8636780
67 + 8636713 = 8636780
79 + 8636701 = 8636780
109 + 8636671 = 8636780
181 + 8636599 = 8636780
193 + 8636587 = 8636780
199 + 8636581 = 8636780
241 + 8636539 = 8636780

Showing the first eight; more decompositions exist.
