Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590894, here are decompositions:

7 + 31590887 = 31590894
17 + 31590877 = 31590894
47 + 31590847 = 31590894
53 + 31590841 = 31590894
61 + 31590833 = 31590894
103 + 31590791 = 31590894
131 + 31590763 = 31590894
157 + 31590737 = 31590894

Showing the first eight; more decompositions exist.
