Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640154, here are decompositions:

137 + 8640017 = 8640154
167 + 8639987 = 8640154
233 + 8639921 = 8640154
251 + 8639903 = 8640154
317 + 8639837 = 8640154
401 + 8639753 = 8640154
443 + 8639711 = 8640154
491 + 8639663 = 8640154

Showing the first eight; more decompositions exist.
