Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589080, here are decompositions:

11 + 31589069 = 31589080
23 + 31589057 = 31589080
53 + 31589027 = 31589080
101 + 31588979 = 31589080
137 + 31588943 = 31589080
233 + 31588847 = 31589080
401 + 31588679 = 31589080
449 + 31588631 = 31589080

Showing the first eight; more decompositions exist.
