Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752644, here are decompositions:

31 + 8752613 = 8752644
71 + 8752573 = 8752644
83 + 8752561 = 8752644
101 + 8752543 = 8752644
107 + 8752537 = 8752644
113 + 8752531 = 8752644
137 + 8752507 = 8752644
167 + 8752477 = 8752644

Showing the first eight; more decompositions exist.
