Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517634, here are decompositions:

17 + 31517617 = 31517634
37 + 31517597 = 31517634
47 + 31517587 = 31517634
61 + 31517573 = 31517634
101 + 31517533 = 31517634
107 + 31517527 = 31517634
167 + 31517467 = 31517634
193 + 31517441 = 31517634

Showing the first eight; more decompositions exist.
