Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500292, here are decompositions:

11 + 31500281 = 31500292
29 + 31500263 = 31500292
71 + 31500221 = 31500292
179 + 31500113 = 31500292
191 + 31500101 = 31500292
269 + 31500023 = 31500292
353 + 31499939 = 31500292
359 + 31499933 = 31500292

Showing the first eight; more decompositions exist.
