Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589904, here are decompositions:

13 + 31589891 = 31589904
37 + 31589867 = 31589904
43 + 31589861 = 31589904
61 + 31589843 = 31589904
127 + 31589777 = 31589904
131 + 31589773 = 31589904
167 + 31589737 = 31589904
173 + 31589731 = 31589904

Showing the first eight; more decompositions exist.
