Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720058, here are decompositions:

31 + 8720027 = 8720058
59 + 8719999 = 8720058
71 + 8719987 = 8720058
97 + 8719961 = 8720058
107 + 8719951 = 8720058
211 + 8719847 = 8720058
227 + 8719831 = 8720058
239 + 8719819 = 8720058

Showing the first eight; more decompositions exist.
