Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743626, here are decompositions:

5 + 8743621 = 8743626
29 + 8743597 = 8743626
37 + 8743589 = 8743626
43 + 8743583 = 8743626
79 + 8743547 = 8743626
113 + 8743513 = 8743626
127 + 8743499 = 8743626
137 + 8743489 = 8743626

Showing the first eight; more decompositions exist.
