Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721634, here are decompositions:

3 + 8721631 = 8721634
17 + 8721617 = 8721634
101 + 8721533 = 8721634
167 + 8721467 = 8721634
191 + 8721443 = 8721634
263 + 8721371 = 8721634
353 + 8721281 = 8721634
443 + 8721191 = 8721634

Showing the first eight; more decompositions exist.
