Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477692, here are decompositions:

23 + 31477669 = 31477692
89 + 31477603 = 31477692
109 + 31477583 = 31477692
131 + 31477561 = 31477692
139 + 31477553 = 31477692
149 + 31477543 = 31477692
179 + 31477513 = 31477692
263 + 31477429 = 31477692

Showing the first eight; more decompositions exist.
