Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718992, here are decompositions:

19 + 8718973 = 8718992
43 + 8718949 = 8718992
181 + 8718811 = 8718992
193 + 8718799 = 8718992
199 + 8718793 = 8718992
283 + 8718709 = 8718992
421 + 8718571 = 8718992
523 + 8718469 = 8718992

Showing the first eight; more decompositions exist.
