Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720632, here are decompositions:

3 + 8720629 = 8720632
5 + 8720627 = 8720632
101 + 8720531 = 8720632
149 + 8720483 = 8720632
293 + 8720339 = 8720632
311 + 8720321 = 8720632
443 + 8720189 = 8720632
461 + 8720171 = 8720632

Showing the first eight; more decompositions exist.
