Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758988, here are decompositions:

37 + 8758951 = 8758988
67 + 8758921 = 8758988
97 + 8758891 = 8758988
109 + 8758879 = 8758988
127 + 8758861 = 8758988
211 + 8758777 = 8758988
241 + 8758747 = 8758988
439 + 8758549 = 8758988

Showing the first eight; more decompositions exist.
