Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461532, here are decompositions:

191 + 31461341 = 31461532
239 + 31461293 = 31461532
251 + 31461281 = 31461532
353 + 31461179 = 31461532
359 + 31461173 = 31461532
383 + 31461149 = 31461532
419 + 31461113 = 31461532
521 + 31461011 = 31461532

Showing the first eight; more decompositions exist.
