Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517434, here are decompositions:

17 + 31517417 = 31517434
23 + 31517411 = 31517434
41 + 31517393 = 31517434
167 + 31517267 = 31517434
191 + 31517243 = 31517434
227 + 31517207 = 31517434
461 + 31516973 = 31517434
593 + 31516841 = 31517434

Showing the first eight; more decompositions exist.
