Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590174, here are decompositions:

13 + 31590161 = 31590174
37 + 31590137 = 31590174
41 + 31590133 = 31590174
53 + 31590121 = 31590174
103 + 31590071 = 31590174
113 + 31590061 = 31590174
137 + 31590037 = 31590174
163 + 31590011 = 31590174

Showing the first eight; more decompositions exist.
