Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670478, here are decompositions:

71 + 8670407 = 8670478
107 + 8670371 = 8670478
197 + 8670281 = 8670478
239 + 8670239 = 8670478
281 + 8670197 = 8670478
389 + 8670089 = 8670478
449 + 8670029 = 8670478
599 + 8669879 = 8670478

Showing the first eight; more decompositions exist.
