Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499202, here are decompositions:

13 + 31499189 = 31499202
19 + 31499183 = 31499202
41 + 31499161 = 31499202
43 + 31499159 = 31499202
139 + 31499063 = 31499202
179 + 31499023 = 31499202
181 + 31499021 = 31499202
199 + 31499003 = 31499202

Showing the first eight; more decompositions exist.
