Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590234, here are decompositions:

23 + 31590211 = 31590234
47 + 31590187 = 31590234
73 + 31590161 = 31590234
97 + 31590137 = 31590234
101 + 31590133 = 31590234
113 + 31590121 = 31590234
163 + 31590071 = 31590234
173 + 31590061 = 31590234

Showing the first eight; more decompositions exist.
