Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624392, here are decompositions:

149 + 8624243 = 8624392
191 + 8624201 = 8624392
233 + 8624159 = 8624392
239 + 8624153 = 8624392
251 + 8624141 = 8624392
263 + 8624129 = 8624392
281 + 8624111 = 8624392
383 + 8624009 = 8624392

Showing the first eight; more decompositions exist.
