Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735490, here are decompositions:

11 + 8735479 = 8735490
37 + 8735453 = 8735490
41 + 8735449 = 8735490
47 + 8735443 = 8735490
61 + 8735429 = 8735490
73 + 8735417 = 8735490
131 + 8735359 = 8735490
149 + 8735341 = 8735490

Showing the first eight; more decompositions exist.
