Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640624, here are decompositions:

23 + 8640601 = 8640624
37 + 8640587 = 8640624
71 + 8640553 = 8640624
131 + 8640493 = 8640624
173 + 8640451 = 8640624
197 + 8640427 = 8640624
233 + 8640391 = 8640624
337 + 8640287 = 8640624

Showing the first eight; more decompositions exist.
