Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518062, here are decompositions:

13 + 31518049 = 31518062
31 + 31518031 = 31518062
61 + 31518001 = 31518062
109 + 31517953 = 31518062
151 + 31517911 = 31518062
211 + 31517851 = 31518062
313 + 31517749 = 31518062
409 + 31517653 = 31518062

Showing the first eight; more decompositions exist.
