Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470532, here are decompositions:

89 + 31470443 = 31470532
173 + 31470359 = 31470532
179 + 31470353 = 31470532
239 + 31470293 = 31470532
311 + 31470221 = 31470532
389 + 31470143 = 31470532
683 + 31469849 = 31470532
719 + 31469813 = 31470532

Showing the first eight; more decompositions exist.
