Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644402, here are decompositions:

5 + 8644397 = 8644402
71 + 8644331 = 8644402
101 + 8644301 = 8644402
149 + 8644253 = 8644402
311 + 8644091 = 8644402
353 + 8644049 = 8644402
383 + 8644019 = 8644402
443 + 8643959 = 8644402

Showing the first eight; more decompositions exist.
