Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644446, here are decompositions:

7 + 8644439 = 8644446
193 + 8644253 = 8644446
233 + 8644213 = 8644446
389 + 8644057 = 8644446
397 + 8644049 = 8644446
449 + 8643997 = 8644446
487 + 8643959 = 8644446
523 + 8643923 = 8644446

Showing the first eight; more decompositions exist.
