Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483170, here are decompositions:

7 + 31483163 = 31483170
53 + 31483117 = 31483170
73 + 31483097 = 31483170
83 + 31483087 = 31483170
101 + 31483069 = 31483170
109 + 31483061 = 31483170
167 + 31483003 = 31483170
179 + 31482991 = 31483170

Showing the first eight; more decompositions exist.
