Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624430, here are decompositions:

37 + 8624393 = 8624430
47 + 8624383 = 8624430
103 + 8624327 = 8624430
107 + 8624323 = 8624430
163 + 8624267 = 8624430
179 + 8624251 = 8624430
181 + 8624249 = 8624430
193 + 8624237 = 8624430

Showing the first eight; more decompositions exist.
