Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726472, here are decompositions:

5 + 8726467 = 8726472
11 + 8726461 = 8726472
23 + 8726449 = 8726472
71 + 8726401 = 8726472
89 + 8726383 = 8726472
109 + 8726363 = 8726472
113 + 8726359 = 8726472
149 + 8726323 = 8726472

Showing the first eight; more decompositions exist.
