Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649136, here are decompositions:

107 + 8649029 = 8649136
113 + 8649023 = 8649136
257 + 8648879 = 8649136
269 + 8648867 = 8649136
389 + 8648747 = 8649136
449 + 8648687 = 8649136
593 + 8648543 = 8649136
599 + 8648537 = 8649136

Showing the first eight; more decompositions exist.
