Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624438, here are decompositions:

127 + 8624311 = 8624438
307 + 8624131 = 8624438
337 + 8624101 = 8624438
379 + 8624059 = 8624438
421 + 8624017 = 8624438
499 + 8623939 = 8624438
541 + 8623897 = 8624438
607 + 8623831 = 8624438

Showing the first eight; more decompositions exist.
