Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523588, here are decompositions:

67 + 31523521 = 31523588
127 + 31523461 = 31523588
181 + 31523407 = 31523588
241 + 31523347 = 31523588
337 + 31523251 = 31523588
367 + 31523221 = 31523588
379 + 31523209 = 31523588
457 + 31523131 = 31523588

Showing the first eight; more decompositions exist.
