Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523120, here are decompositions:

11 + 523109 = 523120
23 + 523097 = 523120
71 + 523049 = 523120
89 + 523031 = 523120
113 + 523007 = 523120
131 + 522989 = 523120
173 + 522947 = 523120
233 + 522887 = 523120

Showing the first eight; more decompositions exist.
