Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607614, here are decompositions:

83 + 31607531 = 31607614
167 + 31607447 = 31607614
191 + 31607423 = 31607614
251 + 31607363 = 31607614
257 + 31607357 = 31607614
317 + 31607297 = 31607614
461 + 31607153 = 31607614
617 + 31606997 = 31607614

Showing the first eight; more decompositions exist.
