Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654870, here are decompositions:

31 + 8654839 = 8654870
61 + 8654809 = 8654870
67 + 8654803 = 8654870
97 + 8654773 = 8654870
109 + 8654761 = 8654870
157 + 8654713 = 8654870
181 + 8654689 = 8654870
229 + 8654641 = 8654870

Showing the first eight; more decompositions exist.
