Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649358, here are decompositions:

5 + 8649353 = 8649358
41 + 8649317 = 8649358
59 + 8649299 = 8649358
131 + 8649227 = 8649358
167 + 8649191 = 8649358
479 + 8648879 = 8649358
491 + 8648867 = 8649358
521 + 8648837 = 8649358

Showing the first eight; more decompositions exist.
