Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691826, here are decompositions:

23 + 8691803 = 8691826
137 + 8691689 = 8691826
173 + 8691653 = 8691826
233 + 8691593 = 8691826
239 + 8691587 = 8691826
317 + 8691509 = 8691826
347 + 8691479 = 8691826
419 + 8691407 = 8691826

Showing the first eight; more decompositions exist.
