Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477814, here are decompositions:

3 + 31477811 = 31477814
61 + 31477753 = 31477814
97 + 31477717 = 31477814
103 + 31477711 = 31477814
157 + 31477657 = 31477814
211 + 31477603 = 31477814
271 + 31477543 = 31477814
307 + 31477507 = 31477814

Showing the first eight; more decompositions exist.
