Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751818, here are decompositions:

37 + 8751781 = 8751818
79 + 8751739 = 8751818
151 + 8751667 = 8751818
199 + 8751619 = 8751818
241 + 8751577 = 8751818
349 + 8751469 = 8751818
367 + 8751451 = 8751818
379 + 8751439 = 8751818

Showing the first eight; more decompositions exist.
