Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517626, here are decompositions:

29 + 31517597 = 31517626
47 + 31517579 = 31517626
53 + 31517573 = 31517626
83 + 31517543 = 31517626
227 + 31517399 = 31517626
233 + 31517393 = 31517626
353 + 31517273 = 31517626
359 + 31517267 = 31517626

Showing the first eight; more decompositions exist.
