Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735642, here are decompositions:

61 + 8735581 = 8735642
79 + 8735563 = 8735642
163 + 8735479 = 8735642
193 + 8735449 = 8735642
199 + 8735443 = 8735642
229 + 8735413 = 8735642
271 + 8735371 = 8735642
283 + 8735359 = 8735642

Showing the first eight; more decompositions exist.
