Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576594, here are decompositions:

11 + 31576583 = 31576594
53 + 31576541 = 31576594
83 + 31576511 = 31576594
167 + 31576427 = 31576594
191 + 31576403 = 31576594
227 + 31576367 = 31576594
311 + 31576283 = 31576594
353 + 31576241 = 31576594

Showing the first eight; more decompositions exist.
