Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477594, here are decompositions:

11 + 31477583 = 31477594
17 + 31477577 = 31477594
23 + 31477571 = 31477594
41 + 31477553 = 31477594
167 + 31477427 = 31477594
293 + 31477301 = 31477594
431 + 31477163 = 31477594
647 + 31476947 = 31477594

Showing the first eight; more decompositions exist.
