Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499300, here are decompositions:

3 + 31499297 = 31499300
61 + 31499239 = 31499300
73 + 31499227 = 31499300
139 + 31499161 = 31499300
163 + 31499137 = 31499300
193 + 31499107 = 31499300
223 + 31499077 = 31499300
277 + 31499023 = 31499300

Showing the first eight; more decompositions exist.
