Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691828, here are decompositions:

29 + 8691799 = 8691828
97 + 8691731 = 8691828
139 + 8691689 = 8691828
239 + 8691589 = 8691828
241 + 8691587 = 8691828
331 + 8691497 = 8691828
347 + 8691481 = 8691828
349 + 8691479 = 8691828

Showing the first eight; more decompositions exist.
