Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726198, here are decompositions:

97 + 8726101 = 8726198
181 + 8726017 = 8726198
199 + 8725999 = 8726198
211 + 8725987 = 8726198
367 + 8725831 = 8726198
499 + 8725699 = 8726198
541 + 8725657 = 8726198
571 + 8725627 = 8726198

Showing the first eight; more decompositions exist.
