Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758558, here are decompositions:

47 + 8758511 = 8758558
59 + 8758499 = 8758558
101 + 8758457 = 8758558
131 + 8758427 = 8758558
167 + 8758391 = 8758558
197 + 8758361 = 8758558
269 + 8758289 = 8758558
359 + 8758199 = 8758558

Showing the first eight; more decompositions exist.
