Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734642, here are decompositions:

3 + 8734639 = 8734642
29 + 8734613 = 8734642
71 + 8734571 = 8734642
131 + 8734511 = 8734642
173 + 8734469 = 8734642
239 + 8734403 = 8734642
269 + 8734373 = 8734642
281 + 8734361 = 8734642

Showing the first eight; more decompositions exist.
