Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691904, here are decompositions:

3 + 8691901 = 8691904
71 + 8691833 = 8691904
101 + 8691803 = 8691904
173 + 8691731 = 8691904
251 + 8691653 = 8691904
281 + 8691623 = 8691904
311 + 8691593 = 8691904
317 + 8691587 = 8691904

Showing the first eight; more decompositions exist.
