Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720104, here are decompositions:

17 + 8720087 = 8720104
23 + 8720081 = 8720104
47 + 8720057 = 8720104
257 + 8719847 = 8720104
401 + 8719703 = 8720104
443 + 8719661 = 8720104
563 + 8719541 = 8720104
683 + 8719421 = 8720104

Showing the first eight; more decompositions exist.
