Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624340, here are decompositions:

13 + 8624327 = 8624340
17 + 8624323 = 8624340
29 + 8624311 = 8624340
73 + 8624267 = 8624340
89 + 8624251 = 8624340
97 + 8624243 = 8624340
103 + 8624237 = 8624340
139 + 8624201 = 8624340

Showing the first eight; more decompositions exist.
