Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518058, here are decompositions:

59 + 31517999 = 31518058
107 + 31517951 = 31518058
149 + 31517909 = 31518058
179 + 31517879 = 31518058
197 + 31517861 = 31518058
359 + 31517699 = 31518058
419 + 31517639 = 31518058
461 + 31517597 = 31518058

Showing the first eight; more decompositions exist.
