Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701040, here are decompositions:

13 + 8701027 = 8701040
31 + 8701009 = 8701040
109 + 8700931 = 8701040
223 + 8700817 = 8701040
241 + 8700799 = 8701040
331 + 8700709 = 8701040
619 + 8700421 = 8701040
757 + 8700283 = 8701040

Showing the first eight; more decompositions exist.
