Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691784, here are decompositions:

53 + 8691731 = 8691784
131 + 8691653 = 8691784
191 + 8691593 = 8691784
197 + 8691587 = 8691784
401 + 8691383 = 8691784
503 + 8691281 = 8691784
617 + 8691167 = 8691784
683 + 8691101 = 8691784

Showing the first eight; more decompositions exist.
