Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636740, here are decompositions:

3 + 8636737 = 8636740
107 + 8636633 = 8636740
113 + 8636627 = 8636740
137 + 8636603 = 8636740
149 + 8636591 = 8636740
191 + 8636549 = 8636740
197 + 8636543 = 8636740
227 + 8636513 = 8636740

Showing the first eight; more decompositions exist.
