Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487614, here are decompositions:

5 + 31487609 = 31487614
71 + 31487543 = 31487614
101 + 31487513 = 31487614
107 + 31487507 = 31487614
167 + 31487447 = 31487614
233 + 31487381 = 31487614
251 + 31487363 = 31487614
383 + 31487231 = 31487614

Showing the first eight; more decompositions exist.
