Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511040, here are decompositions:

7 + 511033 = 511040
97 + 510943 = 511040
109 + 510931 = 511040
151 + 510889 = 511040
193 + 510847 = 511040
223 + 510817 = 511040
331 + 510709 = 511040
349 + 510691 = 511040

Showing the first eight; more decompositions exist.
