Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483130, here are decompositions:

13 + 31483117 = 31483130
37 + 31483093 = 31483130
43 + 31483087 = 31483130
61 + 31483069 = 31483130
79 + 31483051 = 31483130
127 + 31483003 = 31483130
139 + 31482991 = 31483130
157 + 31482973 = 31483130

Showing the first eight; more decompositions exist.
