Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648446, here are decompositions:

113 + 8648333 = 8648446
179 + 8648267 = 8648446
347 + 8648099 = 8648446
353 + 8648093 = 8648446
449 + 8647997 = 8648446
467 + 8647979 = 8648446
479 + 8647967 = 8648446
509 + 8647937 = 8648446

Showing the first eight; more decompositions exist.
