Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517454, here are decompositions:

13 + 31517441 = 31517454
37 + 31517417 = 31517454
41 + 31517413 = 31517454
43 + 31517411 = 31517454
47 + 31517407 = 31517454
61 + 31517393 = 31517454
181 + 31517273 = 31517454
211 + 31517243 = 31517454

Showing the first eight; more decompositions exist.
