Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703128, here are decompositions:

37 + 8703091 = 8703128
67 + 8703061 = 8703128
127 + 8703001 = 8703128
139 + 8702989 = 8703128
307 + 8702821 = 8703128
397 + 8702731 = 8703128
439 + 8702689 = 8703128
541 + 8702587 = 8703128

Showing the first eight; more decompositions exist.
