Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042432, here are decompositions:

5 + 1042427 = 1042432
59 + 1042373 = 1042432
101 + 1042331 = 1042432
173 + 1042259 = 1042432
191 + 1042241 = 1042432
239 + 1042193 = 1042432
311 + 1042121 = 1042432
389 + 1042043 = 1042432

Showing the first eight; more decompositions exist.
