Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641600, here are decompositions:

29 + 8641571 = 8641600
53 + 8641547 = 8641600
59 + 8641541 = 8641600
83 + 8641517 = 8641600
131 + 8641469 = 8641600
167 + 8641433 = 8641600
179 + 8641421 = 8641600
239 + 8641361 = 8641600

Showing the first eight; more decompositions exist.
