Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720464, here are decompositions:

17 + 8720447 = 8720464
47 + 8720417 = 8720464
293 + 8720171 = 8720464
353 + 8720111 = 8720464
383 + 8720081 = 8720464
503 + 8719961 = 8720464
521 + 8719943 = 8720464
617 + 8719847 = 8720464

Showing the first eight; more decompositions exist.
