Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589036, here are decompositions:

19 + 31589017 = 31589036
43 + 31588993 = 31589036
79 + 31588957 = 31589036
103 + 31588933 = 31589036
109 + 31588927 = 31589036
139 + 31588897 = 31589036
223 + 31588813 = 31589036
229 + 31588807 = 31589036

Showing the first eight; more decompositions exist.
