Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472468, here are decompositions:

19 + 31472449 = 31472468
31 + 31472437 = 31472468
109 + 31472359 = 31472468
229 + 31472239 = 31472468
277 + 31472191 = 31472468
337 + 31472131 = 31472468
439 + 31472029 = 31472468
457 + 31472011 = 31472468

Showing the first eight; more decompositions exist.
