Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691630, here are decompositions:

7 + 8691623 = 8691630
37 + 8691593 = 8691630
41 + 8691589 = 8691630
43 + 8691587 = 8691630
47 + 8691583 = 8691630
89 + 8691541 = 8691630
149 + 8691481 = 8691630
151 + 8691479 = 8691630

Showing the first eight; more decompositions exist.
