Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470464, here are decompositions:

127 + 31470337 = 31470464
241 + 31470223 = 31470464
271 + 31470193 = 31470464
313 + 31470151 = 31470464
367 + 31470097 = 31470464
397 + 31470067 = 31470464
541 + 31469923 = 31470464
607 + 31469857 = 31470464

Showing the first eight; more decompositions exist.
