Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939090, here are decompositions:

29 + 939061 = 939090
71 + 939019 = 939090
79 + 939011 = 939090
83 + 939007 = 939090
101 + 938989 = 939090
107 + 938983 = 939090
109 + 938981 = 939090
127 + 938963 = 939090

Showing the first eight; more decompositions exist.
