Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637388, here are decompositions:

47 + 8637341 = 8637388
131 + 8637257 = 8637388
257 + 8637131 = 8637388
269 + 8637119 = 8637388
281 + 8637107 = 8637388
401 + 8636987 = 8637388
467 + 8636921 = 8637388
479 + 8636909 = 8637388

Showing the first eight; more decompositions exist.
