Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720506, here are decompositions:

17 + 8720489 = 8720506
23 + 8720483 = 8720506
29 + 8720477 = 8720506
59 + 8720447 = 8720506
89 + 8720417 = 8720506
167 + 8720339 = 8720506
317 + 8720189 = 8720506
419 + 8720087 = 8720506

Showing the first eight; more decompositions exist.
