Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726740, here are decompositions:

3 + 8726737 = 8726740
17 + 8726723 = 8726740
41 + 8726699 = 8726740
53 + 8726687 = 8726740
107 + 8726633 = 8726740
167 + 8726573 = 8726740
233 + 8726507 = 8726740
293 + 8726447 = 8726740

Showing the first eight; more decompositions exist.
