Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637964, here are decompositions:

11 + 8637953 = 8637964
173 + 8637791 = 8637964
263 + 8637701 = 8637964
347 + 8637617 = 8637964
353 + 8637611 = 8637964
443 + 8637521 = 8637964
641 + 8637323 = 8637964
653 + 8637311 = 8637964

Showing the first eight; more decompositions exist.
