Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501734, here are decompositions:

7 + 31501727 = 31501734
13 + 31501721 = 31501734
73 + 31501661 = 31501734
101 + 31501633 = 31501734
113 + 31501621 = 31501734
151 + 31501583 = 31501734
167 + 31501567 = 31501734
197 + 31501537 = 31501734

Showing the first eight; more decompositions exist.
