Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023818, here are decompositions:

67 + 1023751 = 1023818
97 + 1023721 = 1023818
241 + 1023577 = 1023818
277 + 1023541 = 1023818
331 + 1023487 = 1023818
409 + 1023409 = 1023818
457 + 1023361 = 1023818
541 + 1023277 = 1023818

Showing the first eight; more decompositions exist.
