Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691742, here are decompositions:

11 + 8691731 = 8691742
53 + 8691689 = 8691742
89 + 8691653 = 8691742
149 + 8691593 = 8691742
233 + 8691509 = 8691742
263 + 8691479 = 8691742
359 + 8691383 = 8691742
383 + 8691359 = 8691742

Showing the first eight; more decompositions exist.
