Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726540, here are decompositions:

7 + 8726533 = 8726540
13 + 8726527 = 8726540
19 + 8726521 = 8726540
61 + 8726479 = 8726540
73 + 8726467 = 8726540
79 + 8726461 = 8726540
139 + 8726401 = 8726540
157 + 8726383 = 8726540

Showing the first eight; more decompositions exist.
