Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517332, here are decompositions:

59 + 31517273 = 31517332
89 + 31517243 = 31517332
101 + 31517231 = 31517332
269 + 31517063 = 31517332
293 + 31517039 = 31517332
311 + 31517021 = 31517332
359 + 31516973 = 31517332
443 + 31516889 = 31517332

Showing the first eight; more decompositions exist.
