Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624390, here are decompositions:

7 + 8624383 = 8624390
37 + 8624353 = 8624390
67 + 8624323 = 8624390
79 + 8624311 = 8624390
139 + 8624251 = 8624390
199 + 8624191 = 8624390
211 + 8624179 = 8624390
331 + 8624059 = 8624390

Showing the first eight; more decompositions exist.
