Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493710, here are decompositions:

137 + 31493573 = 31493710
191 + 31493519 = 31493710
197 + 31493513 = 31493710
233 + 31493477 = 31493710
263 + 31493447 = 31493710
389 + 31493321 = 31493710
419 + 31493291 = 31493710
461 + 31493249 = 31493710

Showing the first eight; more decompositions exist.
