Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030520, here are decompositions:

79 + 1030441 = 1030520
103 + 1030417 = 1030520
109 + 1030411 = 1030520
151 + 1030369 = 1030520
163 + 1030357 = 1030520
223 + 1030297 = 1030520
229 + 1030291 = 1030520
307 + 1030213 = 1030520

Showing the first eight; more decompositions exist.
