Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477206, here are decompositions:

43 + 31477163 = 31477206
107 + 31477099 = 31477206
127 + 31477079 = 31477206
139 + 31477067 = 31477206
149 + 31477057 = 31477206
179 + 31477027 = 31477206
353 + 31476853 = 31477206
359 + 31476847 = 31477206

Showing the first eight; more decompositions exist.
