Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747782, here are decompositions:

5 + 8747777 = 8747782
23 + 8747759 = 8747782
59 + 8747723 = 8747782
179 + 8747603 = 8747782
269 + 8747513 = 8747782
293 + 8747489 = 8747782
311 + 8747471 = 8747782
359 + 8747423 = 8747782

Showing the first eight; more decompositions exist.
