Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726398, here are decompositions:

17 + 8726381 = 8726398
41 + 8726357 = 8726398
47 + 8726351 = 8726398
257 + 8726141 = 8726398
311 + 8726087 = 8726398
347 + 8726051 = 8726398
419 + 8725979 = 8726398
449 + 8725949 = 8726398

Showing the first eight; more decompositions exist.
