Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590150, here are decompositions:

13 + 31590137 = 31590150
17 + 31590133 = 31590150
29 + 31590121 = 31590150
61 + 31590089 = 31590150
79 + 31590071 = 31590150
89 + 31590061 = 31590150
113 + 31590037 = 31590150
139 + 31590011 = 31590150

Showing the first eight; more decompositions exist.
