Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651740, here are decompositions:

3 + 8651737 = 8651740
17 + 8651723 = 8651740
23 + 8651717 = 8651740
29 + 8651711 = 8651740
47 + 8651693 = 8651740
101 + 8651639 = 8651740
113 + 8651627 = 8651740
131 + 8651609 = 8651740

Showing the first eight; more decompositions exist.
