Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641782, here are decompositions:

41 + 8641741 = 8641782
73 + 8641709 = 8641782
109 + 8641673 = 8641782
113 + 8641669 = 8641782
131 + 8641651 = 8641782
139 + 8641643 = 8641782
151 + 8641631 = 8641782
179 + 8641603 = 8641782

Showing the first eight; more decompositions exist.
