Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720476, here are decompositions:

5 + 8720471 = 8720476
29 + 8720447 = 8720476
47 + 8720429 = 8720476
59 + 8720417 = 8720476
137 + 8720339 = 8720476
389 + 8720087 = 8720476
419 + 8720057 = 8720476
449 + 8720027 = 8720476

Showing the first eight; more decompositions exist.
