Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636974, here are decompositions:

53 + 8636921 = 8636974
173 + 8636801 = 8636974
233 + 8636741 = 8636974
347 + 8636627 = 8636974
383 + 8636591 = 8636974
431 + 8636543 = 8636974
461 + 8636513 = 8636974
587 + 8636387 = 8636974

Showing the first eight; more decompositions exist.
