Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477544, here are decompositions:

31 + 31477513 = 31477544
37 + 31477507 = 31477544
61 + 31477483 = 31477544
97 + 31477447 = 31477544
193 + 31477351 = 31477544
223 + 31477321 = 31477544
331 + 31477213 = 31477544
337 + 31477207 = 31477544

Showing the first eight; more decompositions exist.
