Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670572, here are decompositions:

13 + 8670559 = 8670572
19 + 8670553 = 8670572
73 + 8670499 = 8670572
139 + 8670433 = 8670572
199 + 8670373 = 8670572
241 + 8670331 = 8670572
271 + 8670301 = 8670572
541 + 8670031 = 8670572

Showing the first eight; more decompositions exist.
