Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670440, here are decompositions:

7 + 8670433 = 8670440
43 + 8670397 = 8670440
67 + 8670373 = 8670440
109 + 8670331 = 8670440
127 + 8670313 = 8670440
139 + 8670301 = 8670440
283 + 8670157 = 8670440
313 + 8670127 = 8670440

Showing the first eight; more decompositions exist.
