Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518060, here are decompositions:

11 + 31518049 = 31518060
23 + 31518037 = 31518060
29 + 31518031 = 31518060
37 + 31518023 = 31518060
53 + 31518007 = 31518060
59 + 31518001 = 31518060
61 + 31517999 = 31518060
97 + 31517963 = 31518060

Showing the first eight; more decompositions exist.
