Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039540, here are decompositions:

3 + 1039537 = 1039540
23 + 1039517 = 1039540
59 + 1039481 = 1039540
71 + 1039469 = 1039540
113 + 1039427 = 1039540
191 + 1039349 = 1039540
197 + 1039343 = 1039540
233 + 1039307 = 1039540

Showing the first eight; more decompositions exist.
