Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523040, here are decompositions:

19 + 523021 = 523040
79 + 522961 = 523040
97 + 522943 = 523040
157 + 522883 = 523040
211 + 522829 = 523040
229 + 522811 = 523040
277 + 522763 = 523040
283 + 522757 = 523040

Showing the first eight; more decompositions exist.
