Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508052, here are decompositions:

13 + 31508039 = 31508052
61 + 31507991 = 31508052
71 + 31507981 = 31508052
101 + 31507951 = 31508052
113 + 31507939 = 31508052
131 + 31507921 = 31508052
139 + 31507913 = 31508052
151 + 31507901 = 31508052

Showing the first eight; more decompositions exist.
