Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463338, here are decompositions:

17 + 31463321 = 31463338
89 + 31463249 = 31463338
191 + 31463147 = 31463338
239 + 31463099 = 31463338
251 + 31463087 = 31463338
359 + 31462979 = 31463338
449 + 31462889 = 31463338
461 + 31462877 = 31463338

Showing the first eight; more decompositions exist.
