Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637338, here are decompositions:

19 + 8637319 = 8637338
37 + 8637301 = 8637338
271 + 8637067 = 8637338
277 + 8637061 = 8637338
331 + 8637007 = 8637338
349 + 8636989 = 8637338
379 + 8636959 = 8637338
421 + 8636917 = 8637338

Showing the first eight; more decompositions exist.
