Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505734, here are decompositions:

3 + 31505731 = 31505734
5 + 31505729 = 31505734
11 + 31505723 = 31505734
41 + 31505693 = 31505734
101 + 31505633 = 31505734
167 + 31505567 = 31505734
233 + 31505501 = 31505734
347 + 31505387 = 31505734

Showing the first eight; more decompositions exist.
