Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589308, here are decompositions:

5 + 31589303 = 31589308
11 + 31589297 = 31589308
17 + 31589291 = 31589308
239 + 31589069 = 31589308
251 + 31589057 = 31589308
281 + 31589027 = 31589308
461 + 31588847 = 31589308
599 + 31588709 = 31589308

Showing the first eight; more decompositions exist.
