Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589004, here are decompositions:

11 + 31588993 = 31589004
47 + 31588957 = 31589004
53 + 31588951 = 31589004
61 + 31588943 = 31589004
71 + 31588933 = 31589004
107 + 31588897 = 31589004
157 + 31588847 = 31589004
191 + 31588813 = 31589004

Showing the first eight; more decompositions exist.
