Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621544, here are decompositions:

53 + 8621491 = 8621544
67 + 8621477 = 8621544
101 + 8621443 = 8621544
131 + 8621413 = 8621544
167 + 8621377 = 8621544
263 + 8621281 = 8621544
307 + 8621237 = 8621544
331 + 8621213 = 8621544

Showing the first eight; more decompositions exist.
