Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640364, here are decompositions:

101 + 8640263 = 8640364
113 + 8640251 = 8640364
167 + 8640197 = 8640364
347 + 8640017 = 8640364
443 + 8639921 = 8640364
461 + 8639903 = 8640364
617 + 8639747 = 8640364
653 + 8639711 = 8640364

Showing the first eight; more decompositions exist.
