Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011520, here are decompositions:

11 + 1011509 = 1011520
89 + 1011431 = 1011520
113 + 1011407 = 1011520
149 + 1011371 = 1011520
239 + 1011281 = 1011520
281 + 1011239 = 1011520
353 + 1011167 = 1011520
383 + 1011137 = 1011520

Showing the first eight; more decompositions exist.
