Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648550, here are decompositions:

7 + 8648543 = 8648550
13 + 8648537 = 8648550
17 + 8648533 = 8648550
19 + 8648531 = 8648550
37 + 8648513 = 8648550
103 + 8648447 = 8648550
137 + 8648413 = 8648550
179 + 8648371 = 8648550

Showing the first eight; more decompositions exist.
