Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500060, here are decompositions:

13 + 31500047 = 31500060
37 + 31500023 = 31500060
43 + 31500017 = 31500060
71 + 31499989 = 31500060
127 + 31499933 = 31500060
139 + 31499921 = 31500060
167 + 31499893 = 31500060
197 + 31499863 = 31500060

Showing the first eight; more decompositions exist.
