Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021672, here are decompositions:

11 + 1021661 = 1021672
101 + 1021571 = 1021672
131 + 1021541 = 1021672
269 + 1021403 = 1021672
383 + 1021289 = 1021672
389 + 1021283 = 1021672
401 + 1021271 = 1021672
419 + 1021253 = 1021672

Showing the first eight; more decompositions exist.
