Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691626, here are decompositions:

3 + 8691623 = 8691626
37 + 8691589 = 8691626
43 + 8691583 = 8691626
157 + 8691469 = 8691626
193 + 8691433 = 8691626
313 + 8691313 = 8691626
379 + 8691247 = 8691626
397 + 8691229 = 8691626

Showing the first eight; more decompositions exist.
