Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483100, here are decompositions:

3 + 31483097 = 31483100
7 + 31483093 = 31483100
13 + 31483087 = 31483100
31 + 31483069 = 31483100
97 + 31483003 = 31483100
109 + 31482991 = 31483100
127 + 31482973 = 31483100
193 + 31482907 = 31483100

Showing the first eight; more decompositions exist.
