Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477144, here are decompositions:

3 + 31477141 = 31477144
197 + 31476947 = 31477144
227 + 31476917 = 31477144
263 + 31476881 = 31477144
401 + 31476743 = 31477144
521 + 31476623 = 31477144
557 + 31476587 = 31477144
593 + 31476551 = 31477144

Showing the first eight; more decompositions exist.
