Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648444, here are decompositions:

31 + 8648413 = 8648444
73 + 8648371 = 8648444
97 + 8648347 = 8648444
127 + 8648317 = 8648444
193 + 8648251 = 8648444
223 + 8648221 = 8648444
313 + 8648131 = 8648444
331 + 8648113 = 8648444

Showing the first eight; more decompositions exist.
