Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630972, here are decompositions:

43 + 8630929 = 8630972
73 + 8630899 = 8630972
139 + 8630833 = 8630972
151 + 8630821 = 8630972
193 + 8630779 = 8630972
223 + 8630749 = 8630972
331 + 8630641 = 8630972
373 + 8630599 = 8630972

Showing the first eight; more decompositions exist.
