Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742382, here are decompositions:

3 + 8742379 = 8742382
23 + 8742359 = 8742382
29 + 8742353 = 8742382
431 + 8741951 = 8742382
449 + 8741933 = 8742382
521 + 8741861 = 8742382
569 + 8741813 = 8742382
641 + 8741741 = 8742382

Showing the first eight; more decompositions exist.
