Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726492, here are decompositions:

13 + 8726479 = 8726492
31 + 8726461 = 8726492
43 + 8726449 = 8726492
109 + 8726383 = 8726492
163 + 8726329 = 8726492
283 + 8726209 = 8726492
349 + 8726143 = 8726492
661 + 8725831 = 8726492

Showing the first eight; more decompositions exist.
