Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690522, here are decompositions:

109 + 8690413 = 8690522
151 + 8690371 = 8690522
163 + 8690359 = 8690522
229 + 8690293 = 8690522
331 + 8690191 = 8690522
349 + 8690173 = 8690522
433 + 8690089 = 8690522
541 + 8689981 = 8690522

Showing the first eight; more decompositions exist.
