Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021598, here are decompositions:

37 + 1021561 = 1021598
157 + 1021441 = 1021598
181 + 1021417 = 1021598
211 + 1021387 = 1021598
229 + 1021369 = 1021598
271 + 1021327 = 1021598
307 + 1021291 = 1021598
337 + 1021261 = 1021598

Showing the first eight; more decompositions exist.
