Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732818, here are decompositions:

11 + 8732807 = 8732818
131 + 8732687 = 8732818
179 + 8732639 = 8732818
191 + 8732627 = 8732818
317 + 8732501 = 8732818
389 + 8732429 = 8732818
401 + 8732417 = 8732818
449 + 8732369 = 8732818

Showing the first eight; more decompositions exist.
