Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477454, here are decompositions:

7 + 31477447 = 31477454
31 + 31477423 = 31477454
103 + 31477351 = 31477454
163 + 31477291 = 31477454
241 + 31477213 = 31477454
313 + 31477141 = 31477454
397 + 31477057 = 31477454
433 + 31477021 = 31477454

Showing the first eight; more decompositions exist.
