Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751618, here are decompositions:

19 + 8751599 = 8751618
41 + 8751577 = 8751618
61 + 8751557 = 8751618
149 + 8751469 = 8751618
151 + 8751467 = 8751618
157 + 8751461 = 8751618
167 + 8751451 = 8751618
179 + 8751439 = 8751618

Showing the first eight; more decompositions exist.
