Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743868, here are decompositions:

31 + 8743837 = 8743868
61 + 8743807 = 8743868
97 + 8743771 = 8743868
151 + 8743717 = 8743868
157 + 8743711 = 8743868
229 + 8743639 = 8743868
271 + 8743597 = 8743868
307 + 8743561 = 8743868

Showing the first eight; more decompositions exist.
