Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722874, here are decompositions:

163 + 8722711 = 8722874
271 + 8722603 = 8722874
397 + 8722477 = 8722874
541 + 8722333 = 8722874
571 + 8722303 = 8722874
577 + 8722297 = 8722874
751 + 8722123 = 8722874
757 + 8722117 = 8722874

Showing the first eight; more decompositions exist.
