Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720546, here are decompositions:

13 + 8720533 = 8720546
67 + 8720479 = 8720546
139 + 8720407 = 8720546
157 + 8720389 = 8720546
199 + 8720347 = 8720546
229 + 8720317 = 8720546
313 + 8720233 = 8720546
409 + 8720137 = 8720546

Showing the first eight; more decompositions exist.
