Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761642, here are decompositions:

3 + 8761639 = 8761642
11 + 8761631 = 8761642
23 + 8761619 = 8761642
41 + 8761601 = 8761642
173 + 8761469 = 8761642
179 + 8761463 = 8761642
353 + 8761289 = 8761642
389 + 8761253 = 8761642

Showing the first eight; more decompositions exist.
