Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499060, here are decompositions:

3 + 31499057 = 31499060
37 + 31499023 = 31499060
67 + 31498993 = 31499060
97 + 31498963 = 31499060
163 + 31498897 = 31499060
181 + 31498879 = 31499060
193 + 31498867 = 31499060
211 + 31498849 = 31499060

Showing the first eight; more decompositions exist.
