Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018784, here are decompositions:

7 + 1018777 = 1018784
73 + 1018711 = 1018784
163 + 1018621 = 1018784
241 + 1018543 = 1018784
271 + 1018513 = 1018784
307 + 1018477 = 1018784
313 + 1018471 = 1018784
337 + 1018447 = 1018784

Showing the first eight; more decompositions exist.
