Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720074, here are decompositions:

3 + 8720071 = 8720074
17 + 8720057 = 8720074
47 + 8720027 = 8720074
113 + 8719961 = 8720074
131 + 8719943 = 8720074
227 + 8719847 = 8720074
257 + 8719817 = 8720074
653 + 8719421 = 8720074

Showing the first eight; more decompositions exist.
