Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690436, here are decompositions:

23 + 8690413 = 8690436
37 + 8690399 = 8690436
59 + 8690377 = 8690436
103 + 8690333 = 8690436
233 + 8690203 = 8690436
263 + 8690173 = 8690436
317 + 8690119 = 8690436
347 + 8690089 = 8690436

Showing the first eight; more decompositions exist.
