Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476358, here are decompositions:

5 + 31476353 = 31476358
41 + 31476317 = 31476358
107 + 31476251 = 31476358
239 + 31476119 = 31476358
449 + 31475909 = 31476358
509 + 31475849 = 31476358
587 + 31475771 = 31476358
677 + 31475681 = 31476358

Showing the first eight; more decompositions exist.
