Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706278, here are decompositions:

37 + 8706241 = 8706278
109 + 8706169 = 8706278
199 + 8706079 = 8706278
271 + 8706007 = 8706278
277 + 8706001 = 8706278
337 + 8705941 = 8706278
367 + 8705911 = 8706278
397 + 8705881 = 8706278

Showing the first eight; more decompositions exist.
