Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670444, here are decompositions:

11 + 8670433 = 8670444
37 + 8670407 = 8670444
47 + 8670397 = 8670444
71 + 8670373 = 8670444
73 + 8670371 = 8670444
113 + 8670331 = 8670444
131 + 8670313 = 8670444
163 + 8670281 = 8670444

Showing the first eight; more decompositions exist.
