Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720076, here are decompositions:

5 + 8720071 = 8720076
19 + 8720057 = 8720076
89 + 8719987 = 8720076
137 + 8719939 = 8720076
173 + 8719903 = 8720076
229 + 8719847 = 8720076
257 + 8719819 = 8720076
263 + 8719813 = 8720076

Showing the first eight; more decompositions exist.
