Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648426, here are decompositions:

13 + 8648413 = 8648426
37 + 8648389 = 8648426
79 + 8648347 = 8648426
103 + 8648323 = 8648426
109 + 8648317 = 8648426
277 + 8648149 = 8648426
313 + 8648113 = 8648426
433 + 8647993 = 8648426

Showing the first eight; more decompositions exist.
