Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499010, here are decompositions:

7 + 31499003 = 31499010
17 + 31498993 = 31499010
19 + 31498991 = 31499010
43 + 31498967 = 31499010
47 + 31498963 = 31499010
61 + 31498949 = 31499010
79 + 31498931 = 31499010
97 + 31498913 = 31499010

Showing the first eight; more decompositions exist.
