Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732890, here are decompositions:

3 + 8732887 = 8732890
11 + 8732879 = 8732890
29 + 8732861 = 8732890
59 + 8732831 = 8732890
71 + 8732819 = 8732890
83 + 8732807 = 8732890
251 + 8732639 = 8732890
263 + 8732627 = 8732890

Showing the first eight; more decompositions exist.
