Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477526, here are decompositions:

13 + 31477513 = 31477526
19 + 31477507 = 31477526
43 + 31477483 = 31477526
79 + 31477447 = 31477526
97 + 31477429 = 31477526
103 + 31477423 = 31477526
127 + 31477399 = 31477526
313 + 31477213 = 31477526

Showing the first eight; more decompositions exist.
