Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589144, here are decompositions:

7 + 31589137 = 31589144
127 + 31589017 = 31589144
151 + 31588993 = 31589144
193 + 31588951 = 31589144
211 + 31588933 = 31589144
331 + 31588813 = 31589144
337 + 31588807 = 31589144
487 + 31588657 = 31589144

Showing the first eight; more decompositions exist.
