Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586004, here are decompositions:

7 + 31585997 = 31586004
31 + 31585973 = 31586004
41 + 31585963 = 31586004
67 + 31585937 = 31586004
101 + 31585903 = 31586004
167 + 31585837 = 31586004
181 + 31585823 = 31586004
193 + 31585811 = 31586004

Showing the first eight; more decompositions exist.
