Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751642, here are decompositions:

13 + 8751629 = 8751642
23 + 8751619 = 8751642
43 + 8751599 = 8751642
79 + 8751563 = 8751642
139 + 8751503 = 8751642
149 + 8751493 = 8751642
173 + 8751469 = 8751642
181 + 8751461 = 8751642

Showing the first eight; more decompositions exist.
