Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691722, here are decompositions:

79 + 8691643 = 8691722
139 + 8691583 = 8691722
181 + 8691541 = 8691722
241 + 8691481 = 8691722
271 + 8691451 = 8691722
331 + 8691391 = 8691722
349 + 8691373 = 8691722
409 + 8691313 = 8691722

Showing the first eight; more decompositions exist.
