Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455364, here are decompositions:

71 + 31455293 = 31455364
167 + 31455197 = 31455364
233 + 31455131 = 31455364
293 + 31455071 = 31455364
461 + 31454903 = 31455364
491 + 31454873 = 31455364
683 + 31454681 = 31455364
881 + 31454483 = 31455364

Showing the first eight; more decompositions exist.
