Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720356, here are decompositions:

17 + 8720339 = 8720356
167 + 8720189 = 8720356
179 + 8720177 = 8720356
269 + 8720087 = 8720356
509 + 8719847 = 8720356
653 + 8719703 = 8720356
977 + 8719379 = 8720356
1049 + 8719307 = 8720356

Showing the first eight; more decompositions exist.
