Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472622, here are decompositions:

11 + 31472611 = 31472622
31 + 31472591 = 31472622
173 + 31472449 = 31472622
263 + 31472359 = 31472622
271 + 31472351 = 31472622
283 + 31472339 = 31472622
331 + 31472291 = 31472622
383 + 31472239 = 31472622

Showing the first eight; more decompositions exist.
