Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703278, here are decompositions:

37 + 8703241 = 8703278
97 + 8703181 = 8703278
127 + 8703151 = 8703278
139 + 8703139 = 8703278
277 + 8703001 = 8703278
439 + 8702839 = 8703278
457 + 8702821 = 8703278
547 + 8702731 = 8703278

Showing the first eight; more decompositions exist.
