Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173090, here are decompositions:

3 + 173087 = 173090
31 + 173059 = 173090
37 + 173053 = 173090
67 + 173023 = 173090
97 + 172993 = 173090
103 + 172987 = 173090
109 + 172981 = 173090
157 + 172933 = 173090

Showing the first eight; more decompositions exist.
