Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640236, here are decompositions:

67 + 8640169 = 8640236
103 + 8640133 = 8640236
127 + 8640109 = 8640236
223 + 8640013 = 8640236
313 + 8639923 = 8640236
337 + 8639899 = 8640236
373 + 8639863 = 8640236
433 + 8639803 = 8640236

Showing the first eight; more decompositions exist.
