Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743840, here are decompositions:

3 + 8743837 = 8743840
23 + 8743817 = 8743840
71 + 8743769 = 8743840
107 + 8743733 = 8743840
167 + 8743673 = 8743840
251 + 8743589 = 8743840
257 + 8743583 = 8743840
269 + 8743571 = 8743840

Showing the first eight; more decompositions exist.
