Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758556, here are decompositions:

7 + 8758549 = 8758556
19 + 8758537 = 8758556
43 + 8758513 = 8758556
73 + 8758483 = 8758556
97 + 8758459 = 8758556
109 + 8758447 = 8758556
127 + 8758429 = 8758556
223 + 8758333 = 8758556

Showing the first eight; more decompositions exist.
