Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477506, here are decompositions:

23 + 31477483 = 31477506
59 + 31477447 = 31477506
79 + 31477427 = 31477506
83 + 31477423 = 31477506
107 + 31477399 = 31477506
127 + 31477379 = 31477506
157 + 31477349 = 31477506
293 + 31477213 = 31477506

Showing the first eight; more decompositions exist.
