Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732842, here are decompositions:

3 + 8732839 = 8732842
11 + 8732831 = 8732842
23 + 8732819 = 8732842
269 + 8732573 = 8732842
353 + 8732489 = 8732842
431 + 8732411 = 8732842
479 + 8732363 = 8732842
491 + 8732351 = 8732842

Showing the first eight; more decompositions exist.
