Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590846, here are decompositions:

5 + 31590841 = 31590846
13 + 31590833 = 31590846
43 + 31590803 = 31590846
83 + 31590763 = 31590846
107 + 31590739 = 31590846
109 + 31590737 = 31590846
113 + 31590733 = 31590846
163 + 31590683 = 31590846

Showing the first eight; more decompositions exist.
