Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021698, here are decompositions:

37 + 1021661 = 1021698
47 + 1021651 = 1021698
71 + 1021627 = 1021698
127 + 1021571 = 1021698
137 + 1021561 = 1021698
157 + 1021541 = 1021698
211 + 1021487 = 1021698
241 + 1021457 = 1021698

Showing the first eight; more decompositions exist.
