Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690544, here are decompositions:

13 + 8690531 = 8690544
67 + 8690477 = 8690544
131 + 8690413 = 8690544
157 + 8690387 = 8690544
167 + 8690377 = 8690544
173 + 8690371 = 8690544
193 + 8690351 = 8690544
211 + 8690333 = 8690544

Showing the first eight; more decompositions exist.
