Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648378, here are decompositions:

7 + 8648371 = 8648378
31 + 8648347 = 8648378
61 + 8648317 = 8648378
127 + 8648251 = 8648378
139 + 8648239 = 8648378
157 + 8648221 = 8648378
199 + 8648179 = 8648378
229 + 8648149 = 8648378

Showing the first eight; more decompositions exist.
