Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021748, here are decompositions:

37 + 1021711 = 1021748
97 + 1021651 = 1021748
127 + 1021621 = 1021748
307 + 1021441 = 1021748
331 + 1021417 = 1021748
367 + 1021381 = 1021748
379 + 1021369 = 1021748
421 + 1021327 = 1021748

Showing the first eight; more decompositions exist.
