Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653784, here are decompositions:

43 + 8653741 = 8653784
67 + 8653717 = 8653784
127 + 8653657 = 8653784
157 + 8653627 = 8653784
193 + 8653591 = 8653784
331 + 8653453 = 8653784
457 + 8653327 = 8653784
487 + 8653297 = 8653784

Showing the first eight; more decompositions exist.
