Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477854, here are decompositions:

13 + 31477841 = 31477854
43 + 31477811 = 31477854
61 + 31477793 = 31477854
73 + 31477781 = 31477854
101 + 31477753 = 31477854
103 + 31477751 = 31477854
131 + 31477723 = 31477854
137 + 31477717 = 31477854

Showing the first eight; more decompositions exist.
