Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726538, here are decompositions:

5 + 8726533 = 8726538
11 + 8726527 = 8726538
17 + 8726521 = 8726538
31 + 8726507 = 8726538
59 + 8726479 = 8726538
71 + 8726467 = 8726538
89 + 8726449 = 8726538
137 + 8726401 = 8726538

Showing the first eight; more decompositions exist.
