Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637892, here are decompositions:

23 + 8637869 = 8637892
71 + 8637821 = 8637892
101 + 8637791 = 8637892
113 + 8637779 = 8637892
191 + 8637701 = 8637892
251 + 8637641 = 8637892
281 + 8637611 = 8637892
383 + 8637509 = 8637892

Showing the first eight; more decompositions exist.
