Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637922, here are decompositions:

53 + 8637869 = 8637922
101 + 8637821 = 8637922
131 + 8637791 = 8637922
173 + 8637749 = 8637922
281 + 8637641 = 8637922
311 + 8637611 = 8637922
401 + 8637521 = 8637922
431 + 8637491 = 8637922

Showing the first eight; more decompositions exist.
