Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485004, here are decompositions:

3 + 31485001 = 31485004
11 + 31484993 = 31485004
101 + 31484903 = 31485004
167 + 31484837 = 31485004
227 + 31484777 = 31485004
233 + 31484771 = 31485004
251 + 31484753 = 31485004
263 + 31484741 = 31485004

Showing the first eight; more decompositions exist.
