Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712622, here are decompositions:

11 + 8712611 = 8712622
89 + 8712533 = 8712622
131 + 8712491 = 8712622
251 + 8712371 = 8712622
311 + 8712311 = 8712622
353 + 8712269 = 8712622
389 + 8712233 = 8712622
449 + 8712173 = 8712622

Showing the first eight; more decompositions exist.
