Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517754, here are decompositions:

5 + 31517749 = 31517754
31 + 31517723 = 31517754
53 + 31517701 = 31517754
101 + 31517653 = 31517754
113 + 31517641 = 31517754
137 + 31517617 = 31517754
157 + 31517597 = 31517754
167 + 31517587 = 31517754

Showing the first eight; more decompositions exist.
