Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470588, here are decompositions:

7 + 31470581 = 31470588
31 + 31470557 = 31470588
41 + 31470547 = 31470588
179 + 31470409 = 31470588
229 + 31470359 = 31470588
251 + 31470337 = 31470588
367 + 31470221 = 31470588
379 + 31470209 = 31470588

Showing the first eight; more decompositions exist.
