Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600250, here are decompositions:

61 + 31600189 = 31600250
151 + 31600099 = 31600250
163 + 31600087 = 31600250
193 + 31600057 = 31600250
211 + 31600039 = 31600250
337 + 31599913 = 31600250
349 + 31599901 = 31600250
373 + 31599877 = 31600250

Showing the first eight; more decompositions exist.
