Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673818, here are decompositions:

37 + 8673781 = 8673818
271 + 8673547 = 8673818
397 + 8673421 = 8673818
457 + 8673361 = 8673818
547 + 8673271 = 8673818
619 + 8673199 = 8673818
631 + 8673187 = 8673818
661 + 8673157 = 8673818

Showing the first eight; more decompositions exist.
