Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020898, here are decompositions:

5 + 1020893 = 1020898
17 + 1020881 = 1020898
59 + 1020839 = 1020898
71 + 1020827 = 1020898
101 + 1020797 = 1020898
191 + 1020707 = 1020898
467 + 1020431 = 1020898
479 + 1020419 = 1020898

Showing the first eight; more decompositions exist.
