Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726840, here are decompositions:

37 + 8726803 = 8726840
79 + 8726761 = 8726840
103 + 8726737 = 8726840
127 + 8726713 = 8726840
163 + 8726677 = 8726840
193 + 8726647 = 8726840
229 + 8726611 = 8726840
271 + 8726569 = 8726840

Showing the first eight; more decompositions exist.
