Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691730, here are decompositions:

41 + 8691689 = 8691730
107 + 8691623 = 8691730
137 + 8691593 = 8691730
149 + 8691581 = 8691730
233 + 8691497 = 8691730
251 + 8691479 = 8691730
317 + 8691413 = 8691730
347 + 8691383 = 8691730

Showing the first eight; more decompositions exist.
