Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507934, here are decompositions:

13 + 31507921 = 31507934
37 + 31507897 = 31507934
97 + 31507837 = 31507934
163 + 31507771 = 31507934
181 + 31507753 = 31507934
373 + 31507561 = 31507934
571 + 31507363 = 31507934
613 + 31507321 = 31507934

Showing the first eight; more decompositions exist.
