Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021472, here are decompositions:

31 + 1021441 = 1021472
43 + 1021429 = 1021472
103 + 1021369 = 1021472
139 + 1021333 = 1021472
181 + 1021291 = 1021472
211 + 1021261 = 1021472
229 + 1021243 = 1021472
313 + 1021159 = 1021472

Showing the first eight; more decompositions exist.
