Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500598, here are decompositions:

29 + 31500569 = 31500598
89 + 31500509 = 31500598
179 + 31500419 = 31500598
191 + 31500407 = 31500598
317 + 31500281 = 31500598
401 + 31500197 = 31500598
449 + 31500149 = 31500598
491 + 31500107 = 31500598

Showing the first eight; more decompositions exist.
