Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500054, here are decompositions:

7 + 31500047 = 31500054
31 + 31500023 = 31500054
37 + 31500017 = 31500054
191 + 31499863 = 31500054
211 + 31499843 = 31500054
251 + 31499803 = 31500054
293 + 31499761 = 31500054
433 + 31499621 = 31500054

Showing the first eight; more decompositions exist.
