Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504310, here are decompositions:

7 + 31504303 = 31504310
109 + 31504201 = 31504310
127 + 31504183 = 31504310
181 + 31504129 = 31504310
223 + 31504087 = 31504310
337 + 31503973 = 31504310
349 + 31503961 = 31504310
379 + 31503931 = 31504310

Showing the first eight; more decompositions exist.
