Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477054, here are decompositions:

3 + 31477051 = 31477054
107 + 31476947 = 31477054
137 + 31476917 = 31477054
173 + 31476881 = 31477054
233 + 31476821 = 31477054
311 + 31476743 = 31477054
431 + 31476623 = 31477054
443 + 31476611 = 31477054

Showing the first eight; more decompositions exist.
