Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500334, here are decompositions:

53 + 31500281 = 31500334
71 + 31500263 = 31500334
113 + 31500221 = 31500334
137 + 31500197 = 31500334
227 + 31500107 = 31500334
233 + 31500101 = 31500334
251 + 31500083 = 31500334
311 + 31500023 = 31500334

Showing the first eight; more decompositions exist.
