Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499006, here are decompositions:

3 + 31499003 = 31499006
13 + 31498993 = 31499006
43 + 31498963 = 31499006
109 + 31498897 = 31499006
127 + 31498879 = 31499006
139 + 31498867 = 31499006
157 + 31498849 = 31499006
193 + 31498813 = 31499006

Showing the first eight; more decompositions exist.
