Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030478, here are decompositions:

37 + 1030441 = 1030478
61 + 1030417 = 1030478
67 + 1030411 = 1030478
109 + 1030369 = 1030478
181 + 1030297 = 1030478
277 + 1030201 = 1030478
367 + 1030111 = 1030478
409 + 1030069 = 1030478

Showing the first eight; more decompositions exist.
