Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724992, here are decompositions:

43 + 8724949 = 8724992
109 + 8724883 = 8724992
193 + 8724799 = 8724992
271 + 8724721 = 8724992
349 + 8724643 = 8724992
373 + 8724619 = 8724992
433 + 8724559 = 8724992
499 + 8724493 = 8724992

Showing the first eight; more decompositions exist.
