Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743826, here are decompositions:

19 + 8743807 = 8743826
73 + 8743753 = 8743826
79 + 8743747 = 8743826
109 + 8743717 = 8743826
193 + 8743633 = 8743826
229 + 8743597 = 8743826
277 + 8743549 = 8743826
313 + 8743513 = 8743826

Showing the first eight; more decompositions exist.
