Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628742, here are decompositions:

113 + 8628629 = 8628742
191 + 8628551 = 8628742
263 + 8628479 = 8628742
293 + 8628449 = 8628742
359 + 8628383 = 8628742
383 + 8628359 = 8628742
389 + 8628353 = 8628742
449 + 8628293 = 8628742

Showing the first eight; more decompositions exist.
