Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477562, here are decompositions:

13 + 31477549 = 31477562
19 + 31477543 = 31477562
79 + 31477483 = 31477562
139 + 31477423 = 31477562
163 + 31477399 = 31477562
211 + 31477351 = 31477562
241 + 31477321 = 31477562
271 + 31477291 = 31477562

Showing the first eight; more decompositions exist.
