Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470232, here are decompositions:

11 + 31470221 = 31470232
23 + 31470209 = 31470232
89 + 31470143 = 31470232
383 + 31469849 = 31470232
419 + 31469813 = 31470232
449 + 31469783 = 31470232
491 + 31469741 = 31470232
509 + 31469723 = 31470232

Showing the first eight; more decompositions exist.
