Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756638, here are decompositions:

5 + 8756633 = 8756638
29 + 8756609 = 8756638
47 + 8756591 = 8756638
71 + 8756567 = 8756638
131 + 8756507 = 8756638
167 + 8756471 = 8756638
179 + 8756459 = 8756638
197 + 8756441 = 8756638

Showing the first eight; more decompositions exist.
