Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500592, here are decompositions:

3 + 31500589 = 31500592
23 + 31500569 = 31500592
83 + 31500509 = 31500592
89 + 31500503 = 31500592
173 + 31500419 = 31500592
239 + 31500353 = 31500592
311 + 31500281 = 31500592
443 + 31500149 = 31500592

Showing the first eight; more decompositions exist.
