Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463100, here are decompositions:

13 + 31463087 = 31463100
17 + 31463083 = 31463100
23 + 31463077 = 31463100
37 + 31463063 = 31463100
131 + 31462969 = 31463100
167 + 31462933 = 31463100
191 + 31462909 = 31463100
199 + 31462901 = 31463100

Showing the first eight; more decompositions exist.
