Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588404, here are decompositions:

5 + 31588399 = 31588404
37 + 31588367 = 31588404
47 + 31588357 = 31588404
53 + 31588351 = 31588404
73 + 31588331 = 31588404
83 + 31588321 = 31588404
97 + 31588307 = 31588404
101 + 31588303 = 31588404

Showing the first eight; more decompositions exist.
