Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477574, here are decompositions:

3 + 31477571 = 31477574
13 + 31477561 = 31477574
31 + 31477543 = 31477574
61 + 31477513 = 31477574
67 + 31477507 = 31477574
127 + 31477447 = 31477574
151 + 31477423 = 31477574
223 + 31477351 = 31477574

Showing the first eight; more decompositions exist.
