Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470262, here are decompositions:

3 + 31470259 = 31470262
41 + 31470221 = 31470262
53 + 31470209 = 31470262
359 + 31469903 = 31470262
401 + 31469861 = 31470262
449 + 31469813 = 31470262
479 + 31469783 = 31470262
521 + 31469741 = 31470262

Showing the first eight; more decompositions exist.
