Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743886, here are decompositions:

3 + 8743883 = 8743886
7 + 8743879 = 8743886
43 + 8743843 = 8743886
79 + 8743807 = 8743886
139 + 8743747 = 8743886
337 + 8743549 = 8743886
373 + 8743513 = 8743886
397 + 8743489 = 8743886

Showing the first eight; more decompositions exist.
