Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021432, here are decompositions:

3 + 1021429 = 1021432
29 + 1021403 = 1021432
59 + 1021373 = 1021432
101 + 1021331 = 1021432
131 + 1021301 = 1021432
149 + 1021283 = 1021432
173 + 1021259 = 1021432
179 + 1021253 = 1021432

Showing the first eight; more decompositions exist.
