Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508276, here are decompositions:

43 + 31508233 = 31508276
73 + 31508203 = 31508276
97 + 31508179 = 31508276
157 + 31508119 = 31508276
193 + 31508083 = 31508276
199 + 31508077 = 31508276
337 + 31507939 = 31508276
379 + 31507897 = 31508276

Showing the first eight; more decompositions exist.
