Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470484, here are decompositions:

41 + 31470443 = 31470484
131 + 31470353 = 31470484
191 + 31470293 = 31470484
263 + 31470221 = 31470484
317 + 31470167 = 31470484
701 + 31469783 = 31470484
743 + 31469741 = 31470484
761 + 31469723 = 31470484

Showing the first eight; more decompositions exist.
