Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637994, here are decompositions:

3 + 8637991 = 8637994
41 + 8637953 = 8637994
173 + 8637821 = 8637994
293 + 8637701 = 8637994
353 + 8637641 = 8637994
383 + 8637611 = 8637994
467 + 8637527 = 8637994
503 + 8637491 = 8637994

Showing the first eight; more decompositions exist.
