Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726042, here are decompositions:

43 + 8725999 = 8726042
79 + 8725963 = 8726042
211 + 8725831 = 8726042
229 + 8725813 = 8726042
373 + 8725669 = 8726042
421 + 8725621 = 8726042
433 + 8725609 = 8726042
613 + 8725429 = 8726042

Showing the first eight; more decompositions exist.
