Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720024, here are decompositions:

37 + 8719987 = 8720024
73 + 8719951 = 8720024
151 + 8719873 = 8720024
193 + 8719831 = 8720024
211 + 8719813 = 8720024
223 + 8719801 = 8720024
277 + 8719747 = 8720024
421 + 8719603 = 8720024

Showing the first eight; more decompositions exist.
