Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656742, here are decompositions:

13 + 8656729 = 8656742
139 + 8656603 = 8656742
181 + 8656561 = 8656742
331 + 8656411 = 8656742
349 + 8656393 = 8656742
373 + 8656369 = 8656742
379 + 8656363 = 8656742
421 + 8656321 = 8656742

Showing the first eight; more decompositions exist.
