Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670538, here are decompositions:

5 + 8670533 = 8670538
29 + 8670509 = 8670538
47 + 8670491 = 8670538
131 + 8670407 = 8670538
167 + 8670371 = 8670538
257 + 8670281 = 8670538
281 + 8670257 = 8670538
347 + 8670191 = 8670538

Showing the first eight; more decompositions exist.
