Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452376, here are decompositions:

167 + 31452209 = 31452376
173 + 31452203 = 31452376
239 + 31452137 = 31452376
383 + 31451993 = 31452376
467 + 31451909 = 31452376
569 + 31451807 = 31452376
647 + 31451729 = 31452376
653 + 31451723 = 31452376

Showing the first eight; more decompositions exist.
