Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477626, here are decompositions:

23 + 31477603 = 31477626
43 + 31477583 = 31477626
73 + 31477553 = 31477626
83 + 31477543 = 31477626
113 + 31477513 = 31477626
179 + 31477447 = 31477626
197 + 31477429 = 31477626
199 + 31477427 = 31477626

Showing the first eight; more decompositions exist.
