Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507964, here are decompositions:

13 + 31507951 = 31507964
43 + 31507921 = 31507964
67 + 31507897 = 31507964
127 + 31507837 = 31507964
193 + 31507771 = 31507964
211 + 31507753 = 31507964
331 + 31507633 = 31507964
373 + 31507591 = 31507964

Showing the first eight; more decompositions exist.
