Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474344, here are decompositions:

37 + 31474307 = 31474344
43 + 31474301 = 31474344
53 + 31474291 = 31474344
127 + 31474217 = 31474344
131 + 31474213 = 31474344
173 + 31474171 = 31474344
233 + 31474111 = 31474344
271 + 31474073 = 31474344

Showing the first eight; more decompositions exist.
