Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500382, here are decompositions:

3 + 31500379 = 31500382
5 + 31500377 = 31500382
29 + 31500353 = 31500382
101 + 31500281 = 31500382
233 + 31500149 = 31500382
269 + 31500113 = 31500382
281 + 31500101 = 31500382
359 + 31500023 = 31500382

Showing the first eight; more decompositions exist.
