Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023520, here are decompositions:

53 + 1023467 = 1023520
59 + 1023461 = 1023520
101 + 1023419 = 1023520
107 + 1023413 = 1023520
131 + 1023389 = 1023520
167 + 1023353 = 1023520
191 + 1023329 = 1023520
257 + 1023263 = 1023520

Showing the first eight; more decompositions exist.
