Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589320, here are decompositions:

3 + 31589317 = 31589320
17 + 31589303 = 31589320
23 + 31589297 = 31589320
29 + 31589291 = 31589320
137 + 31589183 = 31589320
233 + 31589087 = 31589320
251 + 31589069 = 31589320
263 + 31589057 = 31589320

Showing the first eight; more decompositions exist.
