Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657426, here are decompositions:

3 + 8657423 = 8657426
103 + 8657323 = 8657426
373 + 8657053 = 8657426
409 + 8657017 = 8657426
487 + 8656939 = 8657426
523 + 8656903 = 8657426
577 + 8656849 = 8657426
619 + 8656807 = 8657426

Showing the first eight; more decompositions exist.
