Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649002, here are decompositions:

73 + 8648929 = 8649002
79 + 8648923 = 8649002
139 + 8648863 = 8649002
163 + 8648839 = 8649002
211 + 8648791 = 8649002
223 + 8648779 = 8649002
613 + 8648389 = 8649002
631 + 8648371 = 8649002

Showing the first eight; more decompositions exist.
