Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472710, here are decompositions:

11 + 31472699 = 31472710
41 + 31472669 = 31472710
47 + 31472663 = 31472710
173 + 31472537 = 31472710
359 + 31472351 = 31472710
419 + 31472291 = 31472710
449 + 31472261 = 31472710
509 + 31472201 = 31472710

Showing the first eight; more decompositions exist.
