Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624444, here are decompositions:

61 + 8624383 = 8624444
193 + 8624251 = 8624444
223 + 8624221 = 8624444
307 + 8624137 = 8624444
313 + 8624131 = 8624444
421 + 8624023 = 8624444
541 + 8623903 = 8624444
547 + 8623897 = 8624444

Showing the first eight; more decompositions exist.
