Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654940, here are decompositions:

23 + 8654917 = 8654940
43 + 8654897 = 8654940
67 + 8654873 = 8654940
101 + 8654839 = 8654940
103 + 8654837 = 8654940
131 + 8654809 = 8654940
137 + 8654803 = 8654940
167 + 8654773 = 8654940

Showing the first eight; more decompositions exist.
