Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691790, here are decompositions:

59 + 8691731 = 8691790
101 + 8691689 = 8691790
137 + 8691653 = 8691790
167 + 8691623 = 8691790
197 + 8691593 = 8691790
281 + 8691509 = 8691790
293 + 8691497 = 8691790
311 + 8691479 = 8691790

Showing the first eight; more decompositions exist.
