Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500954, here are decompositions:

7 + 31500947 = 31500954
13 + 31500941 = 31500954
31 + 31500923 = 31500954
83 + 31500871 = 31500954
101 + 31500853 = 31500954
137 + 31500817 = 31500954
157 + 31500797 = 31500954
181 + 31500773 = 31500954

Showing the first eight; more decompositions exist.
