Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624408, here are decompositions:

97 + 8624311 = 8624408
157 + 8624251 = 8624408
229 + 8624179 = 8624408
271 + 8624137 = 8624408
277 + 8624131 = 8624408
307 + 8624101 = 8624408
349 + 8624059 = 8624408
439 + 8623969 = 8624408

Showing the first eight; more decompositions exist.
