Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720692, here are decompositions:

3 + 8720689 = 8720692
5 + 8720687 = 8720692
11 + 8720681 = 8720692
179 + 8720513 = 8720692
263 + 8720429 = 8720692
353 + 8720339 = 8720692
503 + 8720189 = 8720692
521 + 8720171 = 8720692

Showing the first eight; more decompositions exist.
