Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640434, here are decompositions:

7 + 8640427 = 8640434
43 + 8640391 = 8640434
97 + 8640337 = 8640434
193 + 8640241 = 8640434
223 + 8640211 = 8640434
421 + 8640013 = 8640434
433 + 8640001 = 8640434
457 + 8639977 = 8640434

Showing the first eight; more decompositions exist.
