Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043540, here are decompositions:

19 + 1043521 = 1043540
61 + 1043479 = 1043540
73 + 1043467 = 1043540
139 + 1043401 = 1043540
163 + 1043377 = 1043540
229 + 1043311 = 1043540
241 + 1043299 = 1043540
331 + 1043209 = 1043540

Showing the first eight; more decompositions exist.
