Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721484, here are decompositions:

3 + 8721481 = 8721484
11 + 8721473 = 8721484
17 + 8721467 = 8721484
41 + 8721443 = 8721484
71 + 8721413 = 8721484
113 + 8721371 = 8721484
173 + 8721311 = 8721484
293 + 8721191 = 8721484

Showing the first eight; more decompositions exist.
