Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640326, here are decompositions:

67 + 8640259 = 8640326
139 + 8640187 = 8640326
157 + 8640169 = 8640326
193 + 8640133 = 8640326
313 + 8640013 = 8640326
349 + 8639977 = 8640326
463 + 8639863 = 8640326
523 + 8639803 = 8640326

Showing the first eight; more decompositions exist.
