Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477658, here are decompositions:

97 + 31477561 = 31477658
109 + 31477549 = 31477658
151 + 31477507 = 31477658
211 + 31477447 = 31477658
229 + 31477429 = 31477658
307 + 31477351 = 31477658
337 + 31477321 = 31477658
367 + 31477291 = 31477658

Showing the first eight; more decompositions exist.
