Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720598, here are decompositions:

17 + 8720581 = 8720598
41 + 8720557 = 8720598
67 + 8720531 = 8720598
101 + 8720497 = 8720598
109 + 8720489 = 8720598
127 + 8720471 = 8720598
151 + 8720447 = 8720598
167 + 8720431 = 8720598

Showing the first eight; more decompositions exist.
