Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057478, here are decompositions:

67 + 1057411 = 1057478
199 + 1057279 = 1057478
229 + 1057249 = 1057478
241 + 1057237 = 1057478
349 + 1057129 = 1057478
607 + 1056871 = 1057478
739 + 1056739 = 1057478
757 + 1056721 = 1057478

Showing the first eight; more decompositions exist.
