Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475004, here are decompositions:

5 + 31474999 = 31475004
7 + 31474997 = 31475004
23 + 31474981 = 31475004
73 + 31474931 = 31475004
131 + 31474873 = 31475004
137 + 31474867 = 31475004
227 + 31474777 = 31475004
241 + 31474763 = 31475004

Showing the first eight; more decompositions exist.
