Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589952, here are decompositions:

29 + 31589923 = 31589952
61 + 31589891 = 31589952
83 + 31589869 = 31589952
109 + 31589843 = 31589952
179 + 31589773 = 31589952
181 + 31589771 = 31589952
193 + 31589759 = 31589952
241 + 31589711 = 31589952

Showing the first eight; more decompositions exist.
