Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004870, here are decompositions:

73 + 1004797 = 1004870
109 + 1004761 = 1004870
127 + 1004743 = 1004870
193 + 1004677 = 1004870
199 + 1004671 = 1004870
211 + 1004659 = 1004870
271 + 1004599 = 1004870
409 + 1004461 = 1004870

Showing the first eight; more decompositions exist.
