Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589088, here are decompositions:

19 + 31589069 = 31589088
31 + 31589057 = 31589088
61 + 31589027 = 31589088
71 + 31589017 = 31589088
109 + 31588979 = 31589088
131 + 31588957 = 31589088
137 + 31588951 = 31589088
191 + 31588897 = 31589088

Showing the first eight; more decompositions exist.
