Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521084, here are decompositions:

37 + 521047 = 521084
43 + 521041 = 521084
61 + 521023 = 521084
103 + 520981 = 521084
127 + 520957 = 521084
163 + 520921 = 521084
271 + 520813 = 521084
337 + 520747 = 521084

Showing the first eight; more decompositions exist.
