Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730826, here are decompositions:

23 + 8730803 = 8730826
29 + 8730797 = 8730826
89 + 8730737 = 8730826
197 + 8730629 = 8730826
353 + 8730473 = 8730826
359 + 8730467 = 8730826
449 + 8730377 = 8730826
557 + 8730269 = 8730826

Showing the first eight; more decompositions exist.
