Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648172, here are decompositions:

23 + 8648149 = 8648172
41 + 8648131 = 8648172
59 + 8648113 = 8648172
61 + 8648111 = 8648172
73 + 8648099 = 8648172
79 + 8648093 = 8648172
89 + 8648083 = 8648172
139 + 8648033 = 8648172

Showing the first eight; more decompositions exist.
