Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589214, here are decompositions:

17 + 31589197 = 31589214
31 + 31589183 = 31589214
47 + 31589167 = 31589214
127 + 31589087 = 31589214
157 + 31589057 = 31589214
197 + 31589017 = 31589214
257 + 31588957 = 31589214
263 + 31588951 = 31589214

Showing the first eight; more decompositions exist.
