Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742794, here are decompositions:

7 + 8742787 = 8742794
157 + 8742637 = 8742794
223 + 8742571 = 8742794
283 + 8742511 = 8742794
331 + 8742463 = 8742794
373 + 8742421 = 8742794
601 + 8742193 = 8742794
607 + 8742187 = 8742794

Showing the first eight; more decompositions exist.
