Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477586, here are decompositions:

3 + 31477583 = 31477586
37 + 31477549 = 31477586
43 + 31477543 = 31477586
73 + 31477513 = 31477586
79 + 31477507 = 31477586
103 + 31477483 = 31477586
139 + 31477447 = 31477586
157 + 31477429 = 31477586

Showing the first eight; more decompositions exist.
