Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751998, here are decompositions:

67 + 8751931 = 8751998
127 + 8751871 = 8751998
139 + 8751859 = 8751998
181 + 8751817 = 8751998
271 + 8751727 = 8751998
331 + 8751667 = 8751998
379 + 8751619 = 8751998
421 + 8751577 = 8751998

Showing the first eight; more decompositions exist.
