Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624542, here are decompositions:

83 + 8624459 = 8624542
149 + 8624393 = 8624542
293 + 8624249 = 8624542
359 + 8624183 = 8624542
383 + 8624159 = 8624542
389 + 8624153 = 8624542
401 + 8624141 = 8624542
431 + 8624111 = 8624542

Showing the first eight; more decompositions exist.
