Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470582, here are decompositions:

19 + 31470563 = 31470582
113 + 31470469 = 31470582
139 + 31470443 = 31470582
173 + 31470409 = 31470582
223 + 31470359 = 31470582
229 + 31470353 = 31470582
359 + 31470223 = 31470582
373 + 31470209 = 31470582

Showing the first eight; more decompositions exist.
