Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461412, here are decompositions:

71 + 31461341 = 31461412
131 + 31461281 = 31461412
233 + 31461179 = 31461412
239 + 31461173 = 31461412
251 + 31461161 = 31461412
263 + 31461149 = 31461412
401 + 31461011 = 31461412
461 + 31460951 = 31461412

Showing the first eight; more decompositions exist.
