Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474442, here are decompositions:

19 + 31474423 = 31474442
79 + 31474363 = 31474442
151 + 31474291 = 31474442
193 + 31474249 = 31474442
229 + 31474213 = 31474442
271 + 31474171 = 31474442
313 + 31474129 = 31474442
331 + 31474111 = 31474442

Showing the first eight; more decompositions exist.
