Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720246, here are decompositions:

13 + 8720233 = 8720246
19 + 8720227 = 8720246
109 + 8720137 = 8720246
127 + 8720119 = 8720246
307 + 8719939 = 8720246
373 + 8719873 = 8720246
433 + 8719813 = 8720246
499 + 8719747 = 8720246

Showing the first eight; more decompositions exist.
